Updated FAWE integration to the latest FAWE build (178).

I updated the FAWE integration to the latest build (178) as requested in #496. There were a fair bit of changes, including but not limited to:

• Changes were primarily Vector -> BlockVector3 and BlockVector2D -> BlockVector2
• Other changes include changed method names.

I used ClipboardFormats.findByFile(File file) to replace ClipboardFormat.STRUCTURE. It seemed to be the best and safest option, seeing as there was no instance of STRUCTURE in the code.

It was playtested very briefly and it worked.

Is this version can be used with FAWE 1.15+? http://ci.athion.net/job/FastAsyncWorldEdit-1.15/
