Improve font resizing commands
Improve font resizing commands

- doom/increase-font-size no longer resets the font when resizing back
  to 0 (causing an inelegant flash of the frame).
- doom/reset-font-size will now reset text-scale, as well, if it is
  being used.
- doom/*-font-size commands have been changed to only affect the current
  frame.
- doom-big-font-mode will now affect all frames (since minor modes can't
  be frame-local).
