* mError status was being reset properly. What I'm thinking happened is that somewhere along the line, a file would miss and return CACHE_ERROR_404. Then, cache.find() would fail because the file was not in the cache, but because mError wasn't reset it would still report CACHE_ERROR_404. In some cases, this would be overwritten (causing the flickering single frame wrong image), and in others this would erroneously report a miss.
* Tested through three demo games and three player games. Shop screen still shows, didn't notice any missing sounds.
* 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()
- fix for issue 108 (mana icon disappears)
- potential fix for issue 110 (victory bonus texts). Need to check
- Fix for issue 100. A better solution would be to "stretch" the cards in hand the way it is done for the rest of the game, but this will do for now as it is a border case
- Fix for issue 55. We'll remove 2 players mode for now, and put it back when/if we get network play
* Some cleaning after r1062 code review.
- Remove code that was never reached.
- Remove a useless function.
- Make GuiPlay treat cards that are both spells and creatures as
creatures and not spells.
DIS additions:cards with Hellbent and some cards with @damaged. Note that "opponent" is not a valid target and "player|opponentinplay" will not work. So for some addition we assume that the creature will never deal damage to its owner (e.g trygon in DIS). Hellbent works fine in the situation described.
