Check "instanceof Minecart" instead of EntityType.

Right now and especially with Minecraft 1.5, one has to account for
several types of minecarts.
Add the command "ncp unkick *".
Check IHaveCHeckType after CheckType.ALL for data removal.

This ensures that "ncp remove *" really removes chat.logins data, for
instance.
Just add to first bucket, since update(...) has been called.
Trim flag inputs for more tolerance.
Allow "default" as flag, which will add the previously set flags.
Adjust lostgorund/fastedge to catch more vacc fp.
Make fight.reach distances (survival) configurable.
Prepare 1.5 blocks with block flags. Add unused stuff.

More like a safety commit.
1. Add compatibility block flags for MC 1.5 blocks.
2. Add commented out / unused stuff (not really for 1.5).
