Minor fix

• Fix horse type detection

And more fixes...

• Fixed giving items to player deleting existing items
• Fixed adding items to inventories ("add X to inventory") not working at all
• Fixed region enter event spam (to get the name of region, wait 1 tick and use %region at location of player%

There might still be some problems with off hand item usability...

Important fixes

• Fixed block events broken on certain Java 8 servers (hopefully)
• Fixed off hand item detection (works, but might break off hand building blocks)
• Fixed some minor things (TheBukor's commit merged in, and edited)

Still a bit unstable.

First release

Probably buggy, but fixes right click events being triggered twice and adds item frame support. Some 1.9 features based of nfell2009's Skript.
