Changed some code to work well with my Addon.

(isMirror, isWooden, isElectricResistant, setMirror, setWooden,
setElectricResistant)
Code not tested.

Added stuff in ZSSItems
(DekuShield.setWooden & MirrorShield.setMirror)

Okay, this SHOULD work...
Eclipse is still not giving any errors...
