Add window size commands and tab navigation hotkeys

Implement hfull (_), vfull (|), sizeeq (=) for window size control in
resize mode, and tabl (J) / tabr (K) for tab navigation across all modes.
All new keycodes are configurable via g:winresizer_keycode_* variables.

Closes #30 (partial: excludes close key already implemented in #29)
