ea17b0cbb6 LibGUI: Start building a way to instantiate GUI from JSON 
My original idea for GUI building tools was to have the "VisualBuilder"
app generate C++ code which in turn programmatically instantiated UI.
That never really materialized in any useful way beyond static UIs.

This is a fresh, new approach: using JSON to declare the UI and parsing
and constructing this UI at runtime. This will allow for way more
dynamic and flexible approaches to GUI development (I think.)

The basic idea is that you pass a JSON string to Widget::load_from_json
and it takes care of the rest.

This first version supports basic box layouts and instantiation of
arbitrary widgets, as long as those widgets have been registered.

This code has some pretty rough edges right now as it's evolving and
we need to figure out a lot of things about how it should work.
Nevertheless, it feels pretty cool. :^)

Also add a few widgets.

b78e13cf2e LibGUI: Make some GUI event getters return const references

e3101c74c6 LibGUI: Use new Bitmap::minimum_pitch method 
Also, make sure that the painter actually draws on a RGB(A) bitmap.

Closes #3460.

9c3a33762b LibGfx: Saner memory usage of indexed bitmaps 
Indexed bitmaps used to allocate four times the required amount of memory.

Also, we should acknowledge that the underlying data is not always RGBA32,
and instead cast it only when the true type is known.

d6673b384e LibGfx: Remove redundant bits() method 
In all circumstances, this returned exactly the same thing as scanline_u8(),
so let's just remove the silly detour.

This does not add any new dependency on Bitmap-internals, because that already existed.

cf429a788c LibGUI: Add Widget override cursor concept 
We got ourselves into a mess by making widgets override the window
cursor whenever they wanted a custom cursor. This patch introduces a
better solution to that issue: per-widget override cursors.

Each widget now has an override cursor that overrides the window
cursor when that widget is hovered.

01ff17d374 LibGUI: Do not paint scrollbar button highlight for scrollbars without scrubber 
If a scrollbar doesn't have a scrubber (because the view it scrolls is
large enough to display all its contents without scrolling), then
it ignores all clicks. We shouldn't draw a hover highlight that suggests
clickability in that case.

158f3b9362 LibGUI: Add a Clipboard API for retrieving a copied Gfx::Bitmap 
The returned bitmap is always going to be a 32-bit RGBA bitmap for now.

2e6d59b7b2 Clipboard: Add a key-value map alongside the clipboard storage

aa70d8c217 LibGUI: Implement trailing whitespace visualization in TextEditor 
This patch adds an optional mode where TextEditor highlights trailing
whitespace characters on each line with a nice reddish dither pattern.

We should probably make this themable and I'm sure it could be nicer
somehow, but this is just a first cut and I do kinda like it. :^)
