Condensed Palette, Bird AI Update

* The Red Bird now records its original altitude on the level and will
  try and return there should it accidentally climb up or down a wall.
  Sometimes goes into a wavy pattern surrounding its original altitude.
* Editor UI: in the default (vertical) toolbar, the Palette now has a
  two column view to show more color choices on screen at once.
* User setting added: hide the touch control hints.
