c485c86015 LibJS: Use macros to enumerate well-known symbols 
Not only is this a much nicer api (can't pass a typo'd string into the
get_well_known_symbol function), it is also a bit more performant since
there are no hashmap lookups.

2ea85355fe LibJS: Start implementing iterable framework, add ArrayIterator 
With the addition of symbol keys, work can now be done on starting to
implement the well-known symbol functionality. The most important of
these well-known symbols is by far Symbol.iterator.

This patch adds IteratorPrototype, as well as ArrayIterator and
ArrayIteratorPrototype. In the future, sometime after StringIterator has
also been added, this will allow us to use Symbol.iterator directly in
for..of loops, enabling the use of custom iterator objects. Also makes
adding iterator support to native objects much easier (as will have to
be done for Map and Set, when they get added).

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.

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.

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.

More inline assembly. I'm still figuring out how to combine templates

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

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.

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.
