Deck Editing

Decks may now be built using the "Development Tools" section of COSIGN. The decks are saved to the default location (/res/decks) in the standard XML format. Default collections may also be used and automatically imported. The parser for the configuration file has been updated to support this. Full deck and collection importing and exporting should be available tomorrow. The code to import is done but hasn't been tied into the data containers yet, so while COSIGN reads everything in it doesn't populate anything.
