Merge pull request #19 from zifnab06/master

Merged.  Thanks very much.

It will be a little while before I have the plugin updated on S.  I also won't be updating KitchenSink on the other servers until they are running 1.6.2 because I intend to add new 1.6.2-specific features to KitchenSink.  I won't remove the CH version of this command until all servers are on 1.6.2.
Add /lock-horse to restrict right-clicks on horses to the owner, and /unlock-horse.
Merge horse changes with upstream.
Add reasonable default for restart time when absent from config.
Uniform format for all logged drops, includes data value and enchants. Fixed horse lock/unlock. Cleaned up imports.
Forgot to remove trace.
Add an option to make riderless tamed horses invulnerable.
Added recipes for horse armour, saddles and nametags.
