Cursor/Keypad Support
Sadly Cursor/Keypad support is less straightforward than it should be.
The various terminal emulators/consoles choose to differentiate the
cursor and keypad keys (with modifiers) in different ways (if at all!).
Furthermore they use different code set sequences for each key only
a subset of which the various curses libraries recognize. Partly due
to incomplete termcap/terminfo entries and partly due to inherent
limitations of those terminal capability databases.
I give curses first crack at decoding the sequences. If it fails to decode
it we check for common ESC-prefixed sequences.
All cursor/keypad results are translated into standard rogue movement
commands.
Unmodified keys are translated to walk commands: hjklyubn
Modified (shift,control,alt) are translated to run commands: HJKLYUBN
