* Fix a bug where valid directories would be ignored and invalid ones
would be accepted for profiles and themes.
* Fix a compilation fault when compiling in debug mode.
- removed some unused code. Please review!
- Added protection from() auto keyword. It is still possible to use protection from [color] in abilities, but when it is not possible, please use protection from([target]) in auto=
* Metadata is currently only used in exactly one place: the set's "Pretty Name" is displayed when the set is first unlocked.
* WGuiImage now has a function to set scaling.
* Confirmable options used to only check for confirmation when selecting another option. They now autoconfirm when saving & exiting. This bug could possibly result in loading the wrong theme. Fixed.
* Changing profiles, canceling, then changing to the profile again could also result in improper theme loading. Fixed.
* The alternate theme is just useful for testing themes, but please comment on the changes to the main theme.
* Options reading and initializing separated from UI.
* Options UI abstracted a bit, made more easily extensible.
* With some extension, the options UI could be used as the basis for more complicated themes, if we load a file and use it to do stuff like GameStateOptions::Start()
-Issue 26: added an option for Mana Display. This needs a bit testing, but it should also lower the priority of "manapool slowness" as this mode probably fixes performance issue as well.
-I can't seem to be able to "save" some options (hand position, mana display) ion the windows version, does this change break something ?
* 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.
