3a62029dee Base: Add special icons for the home directory 
It's filetype-folder but with little houses on them. :^)

9710c9742c LibGUI+FileManager: Add setting for showing/hiding dotfiles 
GUI::FileSystemModel can now be told to display (or not display) files
whose name start with a dot (other than . and ..)

ad57a2f18b FileManager: Use new TextBox::DisplayOnly mode in the properties dialog 
Use this instead of disabling the name TextBox. This looks a little bit
nicer than the grayed-out appearance. :^)

76e34968fa Demos: Setup window icon for Mouse demo 
The icon was set in the launcher, and the About dialog, but was
missing form the actual window.

e4b068aec5 UserspaceEmulator: Fix buggy IDIV instructions 
These were not doing mashing together the signed double-size results
correctly and lost bits in the signed/unsigned casting process.

9e6d002660 UserspaceEmulator: Fix buggy IMUL instructions 
These were not recording the higher part of the result correctly.
Since the flags are much less complicated than the inline assembly
here, just implement IMUL in C++ instead.

70cb4491d7 AK: Use "signed char" as the opposite of "unsigned char" 
I totally forgot about the C++ basics here. There are three distinct
types: "char", "signed char" and "unsigned char". Whether "char" is
signed or unsigned is implementation specific.

02882d5345 UserspaceEmulator: Add single-operand MUL and DIV instructions 
These are the unsigned variants. Signed variants sold separately.

30d512144e UserspaceEmulator: Implement the BSF and BSF instructions 
BSF maps nicely to __builtin_ctz(), but for BSR we have to bust out
some inline assembly to get exactly what we want.

a4b2d6cf1e LibGUI: Set parent icon, margins and disable resize for InputBox 
Gives a more compact, uniform appearance to input boxes.

d976b31ef6 LibGUI: Paint slider knob as indented when disabled 
Better visual feedback when sliders won't budge.

19e883e45a WidgetGallery: Add more widgets 
Adds combo and input boxes + more variation for existing widgets.

a98d960ad4 Taskbar: Use Name from .af file as tooltip 
With this, System Monitor has "System Monitor" instead of
"SystemMonitor" as tooltip, matching the app's title bar
and menu bar title.

Same for File Manager and Text Editor.

82c38f6fdf WindowServer: Decide on a window title before measuring its width 
If we add "(Not responding)" to the title of an unresponsive window,
the title rect needs to be wider or we'll have text-on-stripes.

Thanks to @SharpOB for reporting this bug!

becbf36711 UserspaceEmulator: Fix XCHG_AX_reg16 overwriting entire EAX 
This instruction should only write to the lower 16 bits (AX)

8ec8ec8b1c Kernel: Remove special-casing of sys$gettid() in syscall entry 
We had a fast-path for the gettid syscall that was useful before
we started caching the thread ID in LibC. Just get rid of it. :^)

75500b449c UserspaceEmulator: Fix every line in backtraces showing EIP 
Oops, we're supposed to show the return address for each frame, not the
current EIP every time. :^)

06669f3f0f UserspaceEmulator: Implement IMUL_RM8 and IMUL_RM32 
These are both a little tricky since they produce a result wider than
the inputs.

51b2b0d5e5 WindowServer: New title bar vars for themes 
The theming system can now control title bar height, title button
size, title stripe color and the title text shadow color.
The implemented theme metrics system could be later extended to LibGUI
to allow themes to change widget padding, border width, etc.

c969b8390d Kernel: Make all 6 VirtualConsoles available via shortcut 
Add all 6 shortcuts even if the switch between VirtualConsoles is
currently not available in the graphical console.

Also make the case statement more compact.

d8fa8c5f82 Kernel: Ensure there are all VirtualConsoles properly initialized 
It is possible to switch to VirtualConsoles 1 to 4 via the shortcut
ALT + [1-4]. Therefor the array of VirtualConsoles should be guaranteed
to be initialized.

Also add an constant for the maximum number of VirtualConsoles to
guarantee consistency.

971a42a816 Kernel: Make the VirtualConsole index const unsigned instead of unsigned 
const:
The index should not be modified in the constructor to avoid unexpected
behavior

df58ea808e UserspaceEmulator: Skip freed mallocations in reachability scan 
Something being reachable from a freed mallocation doesn't make it
actually reachable.

Thanks to Jonas Bengtsson for spotting this! :^)

27aa2e5841 UserspaceEmulator: Reset malloc backtrace on mallocation reuse 
If a previously-freed malloc chunk is reused, forget any old backtraces
and save a new malloc backtrace.

869a3e2cf3 LibC: Notify UserspaceEmulator about BigAllocationBlock mallocs 
We were forgetting to inform UE about these, which caused it to believe
subsequent calls to free() were invalid.

f591157eb8 WindowServer: Fix picking new active window after destroy 
We need to mark windows as destroyed and not consider them
when picking a new active window. Fixes lost focus after
closing some windows.

603c17262c WindowServer: Fix traversing modal stack 
When walking the modal window stack upwards, we need to check if
the top modal window is still a descendant of the window that
the parent is blocked by. Fixes not all windows being brought to
the front when trying to active a parent in the middle of the
modal window stack.
