Started re-writing the shop code to use the ShopItem struct and new setup
Added output debugging for the Shop array
Merge branch 'master' into shoprewrite
Merge branch 'master' into shoprewrite, probably broke half the fucking universe in the process
Finished the base shop structure, next is ShopBuildPages()... Help
Shield page is now built properly
Extras and Brutal Doom compatibility, next is DoomRL... Double help
Finished re-adding all the DRLA stuff
Re-wrote the shop list display code
Implemented cursor checking and buy checking for the Rank limiting of items
Ranking up will now tell you if you've unlocked any new items in the shop
Gave most items a rank requirement, Fixed some bugs
