Save/restore window views when shrinking/restoring

fixes #29
Fix folding around functions
only check possible directions in GetMovementDirection

just a small optimization, but will be more critical if we end up
checking more than one window in each direction
Fix indent
Support jumps to non-adjacent windows

fixes #23
Add functions for pausing and unpausing

these are useful for debugging or running windo commands without messing
up splits
