LibGUI: Fix keybind conflicts in TreeView
...
Changes the shortcut to expand and collapse subtrees from alt to
ctrl+right/left arrows in TreeView. The current shortcuts conflict
with applications that already have navigation controls bound to alt
like file manager.

LibGUI: Only report toggled directories once on subtree collapse/expansion

This prevents redundant calls to on_toggle for the same indices when
subtrees are collapsed or expanded.

not terribly important since we're a userspace-only emulator anyway.

UserspaceEmulator: Make mmap'ed memory track read/write protection

Here's the first time we get a taste of better information than the
real hardware can give us: unlike x86 CPUs, we can actually support
write-only memory, so now we do!
While this isn't immediately useful, it's still pretty cool. :^)

UserspaceEmulator: Pass arguments through to emulated process

Ultimately we'll want to support passing some options to the emulator
as well, but for now just pass all arguments (except argv[0] of course)
through to the emulated process.
This is still not perfect, but slightly better than what we had before.

Default Fonts: Tweak 'F' and 'W'
...
In all default fonts, make the lower bar of the F one pixel shorter to
match the middle bare of the E.
Make the W in CsillaThin a bit shorter on the sides and make it
go less high in the middle. This makes it look more like the W in
CsillaBold, makes the middle high spot in W match the height of
the same spot in X Y E F H. Making it shorter on the side makes
the letter look better when its next ot other full-width letters,
e.g. in "WWW".
Make the w in Katica10 match new new W in CsillaThin. The bold
letters already match, and in general it looks like Csilla is
a monospace version of Katica.

UserspaceEmulator: Add basic TLS (thread-local storage) support

The SoftMMU now receives full X86::LogicalAddress values from SoftCPU.
This allows the MMU to reroute TLS accesses to a special memory region.
The ELF executable's PT_TLS header tells us how to allocate the TLS.
Basically, the GS register points to a magical 4-byte area which has
a pointer to the TCB (thread control block). The TCB lives in normal
flat memory space and is accessed through the DS register.
