75b8f4e4e6 LibGUI: Make focus events more aware of why focus is changing 
This patch adds GUI::FocusEvent which has a GUI::FocusSource.
The focus source is one of three things:

- Programmatic
- Mouse
- Keyboard

This allows receivers of focus events to implement different behaviors
depending on how they receive/lose focus.

19ac1f6368 Revert "Unicode: s/codepoint/code_point/g" 
This reverts commit ea9ac3155d.
It replaced "codepoint" with "code_points", not "code_point".

ea9ac3155d Unicode: s/codepoint/code_point/g 
Unicode calls them "code points" so let's follow their style.

ca93c22ae2 LibGUI: Turn GUI::Application::the() into a pointer 
During app teardown, the Application object may be destroyed before
something else, and so having Application::the() return a reference was
obscuring the truth about its lifetime.

This patch makes the API more honest by returning a pointer. While
this makes call sites look a bit more sketchy, do note that the global
Application pointer only becomes null during app teardown.

I'm sure we can find many interesting uses for this! :^)

b8498dc55e LibVT: Add incremental UTF-8 parsing to the terminal input handler 
Instead of relying on the GUI code to handle UTF-8, we now process

This means that you can now show emojis in the terminal and they will
only take up one character cell each. :^)

901d2e3236 LibVT: Make selection follow terminal history scrollback :^) 
The buffer positions referred to by a VT::Position now include history
scrollback, meaning that a VT::Position with row=0 is at the start of
the history.

The active terminal buffer keeps moving in VT::Position coordinates
whenever we scroll. This allows selection to follow history. It also
allows us to click hyperlinks in history.

Fixes #957.

Improve this by implementing basic "click" semantics instead.

This patch also introduces the ability to prevent link opening if you
want to force selection instead. Hold shift and we will not open links.
