Add support for FAWE

[prldm]

Could you please add support for FAWE (FastAsyncWorldEdit)? "FAWE is a fork of WorldEdit that has huge speed and memory improvements and considerably more features."

Should be doable, but I'll look into this and follow up if it's cool with Geitenijs, I know there is some discussion of switching to async loading for obvious performance reasons. Looking to bring that feature in alongside the new permission system (hopefully by the end of this year?) :)

I'd like to second this request :)

[ErythroCraft]

Please give support for AsyncWorldEdit first.

Better late than never... Added in 1.7.0
