Kitserver 12.1.0 by juce - GDB support

KSERV module with GDB. No extra kits support yet, but a couple new things to note this year:
1. Team IDs are used in map.txt, instead of indices. Read the documentation to find out more info about it
2. New feature: European kits for club teams (See Arsenal in sample GDB) - those are used in UEFA Champions League and Europa League. Just name the kits folders: euro-ga, euro-gb, euro-pa, and euro-pb, and that's all there is to it.
