Fixes to alt-char-set. Bit dubious.
Use constant TAB_SIZE (instead of literal 8).
Fix bug that was causing crash (spurious comma corrupting logic).
Experimental resize support (doesn't work).
Implemented CHT, CBT and TBC (tabulation).
Embed the terminal dimensions in the title.
Dodgy implementations of IND and NEL.
Comment only: RI - Reverse Line Feed
Comment only: CPL - Cursor Preceding Line
Added moveCursor()/tabCursor().
Try xcb_aux_sync() instead of xcb_flush().
Key Terminal::CharSub of ASCII, not UTF-8.
Checkpoint: separated vt state-management out of Terminal.
