Very minor update, mostly released to deal with one bug relating to Market billing:
- Rolled back our change to the appearance of full-text highlighting from 2.3.6, since a few people found the new one distracting.
- Cleaned up the look of buttons in Night Mode a bit.
- Prevented devices from sleeping during the initial data file download.
- Fixed a bug that caused problems for users repeatedly Restoring Market Purchases.
- Fixed a bug that caused the background of the flashcard drawing box to be partially white (and therefore useless) in Night Mode
- Fixed a bug that caused repeated custom font installs in the same session to fail on devices running Android 4.0.
