Jeck - Added full filtering system to deck editor and shop. I've spent 24hours on pure debugging, but there are likely a couple bugs I've missed. So please, if you find something, make an issue of it! :P Also split OptionItem classes into separate files, and added support for mixed-set boosters (which I think are way, way cool).
