minor update: added level 1 to 5 of "layered" puzzle area, made loading screen messages more uniform, dialog for fairies and merchants now uses content defined in xml, exception handling for randomly reoccuring exception in shadow map drawing
Merge branch 'master' of https://github.com/annsimon/candyland
major update: actions now also use new parser, old actions no longer work

minor update: dialogs can display special characters ä, ü, ö, ß by writing !ae!, !ue!, !oe!, !ss! in the xml/tmx file
shadowmap exception causes crash again for now (just catching the exception was not enough to keep the game running - exception occurs after tabbing out on fullscreen -> sometimes messes up draw method)
