51bfc6c6b3 LibJS: Renamed Object::GetOwnPropertyReturnMode to Object::PropertyKind 
This enum will be used by iterators, so it makes sense to use a more
general name.

b8cf07166f Piano: Handle octave slider jumps of greater than 1 
The previous slider handler relied on the new value being 1 different
than the previous.

fixes #1163.

7241b9ca0c LibJS: Remove a few superfluous exception checks 
We don't need to check for exceptions when defining properties on an
array we literally created ourselves a few lines earlier.

7596ae4596 UserspaceEmulator: Implement the RET instruction 
We can now return from a CALL! :^)

0f63d8c9b4 UserspaceEmulator: Symbolicate disassembly output :^) 
Since we have the ELF executable handy, we can actually symbolicate the
disassembly trace output really easily. Very cool! :^)

0a448ee960 UserspaceEmulator: Fix broken inline assembly for asymmetric op_foos 
When the Destination and Source of an op_foo were types of different
sizes, the generated assembly was not filling up the "source" register
fully in some cases. This led to incorrect results.

ae1d14bc7a UserspaceEmulator: Load the target executable ELF semi-properly :^) 
This patch adds a basic ELF program loader to the UserspaceEmulator and
creates MMU regions for each PT_LOAD header. (Note that we don't yet
respect the R/W/X flags etc.)

We also turn the SoftCPU into an X86::InstructionStream and give it an
EIP register so we can actually execute code by fetching memory through
our MMU abstraction.

7d41b95071 UserspaceEmulator: Tweak INC and SAR helpers to not be SoftCPU members 
It's quite nice having these as compartmentalized free functions.

e852768ba6 UserspaceEmulator: Add the INC and ADD instructions 
More inline assembly. I'm still figuring out how to combine templates
and inline assembly, but it's turning out pretty cool. :^)

12ab46def9 UserspaceEmulator: Give SoftCPU an API for evaluating jump conditions 
There are 16 conditions and they're all based on a combination of the
CPU flags.

e5afe6a579 UserspaceEmulator: Implement the CMP family of instructions 
These are identical to SUB, except they don't store the result (they
only upate the arithmetic flags.)

8d5fde440a FileManager: Specify "Open in Text Editor" action as default in context menu 
Since double-clicking the item would trigger the "Open in Text Editor"
action, specify it as the default action when displaying the
context menu.

1c1ab71692 WindowServer/LibGUI: Add default menu items and allow default action for context menu 
By specifying an optional Action for Menu::popup an application
can specify what item should be displayed as a default item.

fc4e01a3c9 WindowServer: Add support for default MenuItem 
This allows marking a MenuItem as a default action, e.g. in a
context menu for an action that reflects what e.g. a double click
would perform.

Also enhance the window menu to mark the close action as the
default, and when double clicked perform that action.

Fixes #1289

684b04e02a WebServer: Allow the user to specify the base directory 
This commit makes the WebServer accept a base path to serve.
This makes taking files out of the system significantly more simple
(depending on whom you ask).

7b5ffe67cf LibWeb: Check if layout node is still present after dispatch_event 
Fixes https://github.com/SerenityOS/serenity/issues/2638

Dispatching an event can change the document. Therefore another check
for the layout_root needs to be done.

on an x86 target anyway. :^)

f8b38eabeb UserspaceEmulator: First cut of generic instruction implementations 
Let's use C++ templates to implement the generic parts of instructions.
There are tons of them with the same set of inputs, just different
behavior. Templates are perfect for this.

3a1cf9505d LibX86: Store Instruction's segment prefix as Optional<SegmentRegister>

f1801cfb28 UserspaceEmulator: Fix a Clang warning 
Clang didn't like default construction of PartAddressableRegister,
so let's just use memset() then.
