Phase 3 optimization

[htv04]

This pull request addresses issues #3 and #10 by making the following changes:

• The phase 3 sprites used for Tricky, Hank, Boyfriend, and Girlfriend have all been rescaled via their files. The island background was rescaled as well.
  • The scaling method used was bicubic.
• The phase 3 XML texture atlases were rescaled using this Python script I wrote.
• The phase 3 sprite offsets, stage setup, and stage coordinates were changed by hand to be as accurate as possible.

Additionally, I tweaked the "jaws" transition so that the jaws sprite does not move as much between transitions.

These changes bring the memory usage of the game from 4-5 GB down to 2-3 GB. They also improve both the game's initial loading time and phase 3's performance since the game no longer applies as much scaling.

Compiled build for Win64 platforms can be found here, for those who want to test these changes out.
