Extended %conf:TOKEN% replacement to allow SRG entries.

For example (with the 1.5.2 mappings):

%CL:net/minecraft/client/entity/EntityOtherPlayerMP% -> bfk
%FD:net/minecraft/util/MovementInput/sneak% -> bfh/d
%MD:net/minecraft/client/model/ModelIronGolem/setLivingAnimations (Lnet/minecraft/entity/EntityLiving;FFF)V% -> bcu/a (Lng;FFF)V

As with the usual conf tokens, you probably want to put these in strings.
