cd74902f89 Charsets 
Initial charset support. This gets a lot of stuff working but still has some critical (but not very real world) limitations.

Implements:

  * All charset slots G0 to G3
  * All shifting commands to shift into GL and GR
  * Single shift commands `ESC N` and `ESC O`
  * UTF8, ASCII, British, and DEC Special Graphics character sets

Notably missing:

  * A number of rarely used charsets
  * NRC handling
  * Disabling UTF-8 mode

All the missing stuff is very edge case... but necessary for correctness.

50409271a3 Mouse Reporting #8 
Implements all known formats and event types for mouse reporting. This makes vim, htop, etc. handle mouse events!

Mouse formats:

  * X10
  * UTF-8
  * SGR
  * urxvt
  * SGR Pixels

Event types:

  * X10
  * "Normal" - mouse button press/release, including scroll wheel
  * "Button" - "Normal" + mouse motion events while a button is pressed
  * "Any" - "Normal" + mouse motion events at anytime (even if a button is not pressed)
