- fix issue 89 and issue 90 - In the future, we will probably want cardSelector to handle CardDisplay somehow (although carddisplay is used in the Shop as well...)
- fix issue 20 (triangle button usage inplay)
- close issue 27 (gold effect on the gold bar). Please feel free to change the gold glow if you come up with something better, but I consider this perfectly releasable now
- code cleanup
