drochner bbb4f765cc Improvements to the VT100 emulation:
-display DEC special graphics and DEC technical characters as far as
  possible
-implement the font switching controls (need documentation!)
-behave well if double-width characters are requested
-simplify the state machine: store CSI command modifiers in variables
  instead of dedicating own states to each of them
