Jeck - Profile and cache improvements, booster duplicate likelihood reduced.

* Cache now tracks missing textures for RetrieveQuad, not just RetrieveCard/RetrieveTexture.
* Profile options are no longer overwritten when switching profiles.
* Main menu notifies of alternate profile- "Database: X" becomes "Profile: Y of X cards."
* Boosters iterates through cards, replacing duplicates. Stops after 15 tries to prevent infinite loops on small sets.
* Very simplistic theme switcher, only displays when alternate themes are present.
