Trolls Outta Luckland - 1.1.0b

Tested with: Python 2.5.4, Pygame 1.9.1.

• Fonts got a facelift.
• Fps class now uses font name.
• Changed Destroyer class to drop a load of slowly moving mines. Number of mines increase with game difficulty.
• Changed scoring for missiles to put them more in line with mines: shooting yields low score to discourage commendation farming; on-screen when completing level gives 5X the PATROL score to encourage some commendation boosting strategies; death gives nothing.
• Made enemy laser fire a little less aggressive. With lasers, missiles, mines, and ramming craft there is a lot going on during the peaks.
• Added F12, RMB, LMB, and Visible Pointer to HUD.
• High scores now have commas.
• Changes for Pygame 1.8.1 compatibility:
  • In enemy.py, powerups.py, ui.py, utils.py: replaced rect.copy() with pygame.Rect(rect).
  • In gumm_sound.py: replaced mixer.pre_init(buffer=1024) with mixer.pre_init(0,0,0,1024).
• Narrowed song selection.
• Added ui.TextReader class for in-game Help and Credits.
• Fixed: Sky no longer layers planets behind galaxies.
• Fixed: utils.load_image(): using surface.copy() on a cached image no longer produces a copy with alpha=0. It now preserves the original alpha. (Bug in Surface.copy()?)
