Issue#361

- fixes all known iOS8 bugs and warnings
- two separate development targets for iOS7.1 and iOS8.0
- fix SearchStoreViewController storyboard issue
- move brick-object references to parser
- minor improvements for player-logic

Important:
suppressed all deprecation warnings for UISearchDisplayController in SearchStoreViewController
Should be replaced by UISearchController when support for iOS7 is not needed any more.
Of course, there is a way to support both UISearchDisplayController for iOS7 and UISearchController for iOS8 right now, but this requires us to maintain two separate storyboards.
