Additional Block Material API's

Faster version for isSolid() that utilizes NMS's state for isSolid instead of the slower
process to do this in the Bukkit API

Material#isSolid uses a large switch statement which isn't as performant vs a simple boolean return

Adds API for buildable, replaceable, burnable too.
