Non Anvil improvements:
- Added command `/caves` - generates caves
- Added command `/ores` and `/ore` - generates ores
- Added brush `/br layer` for placing multiple layers on a surface
- Added brush `/br popschem` for placing schematics on a surface`
- Added hollow polyhedral region select `//sel polyhedral`
- Added smoothing of snow layers `//smooth -s`
- Added heightmap of snow layers `//br height -l`
- Added surface spline brush `/br sspline`
- Added multi-clipboard pattern #fullcopy[:file|folder|url[:rotate=false]]

FAWE ANVIL:
This update drastically improves the performance of the Anvil API, fixes outstanding issues, and adds a lot more capabilities (from a developers standpoint).

Performance wise, ANVIL can now push out somewhere around 500,000,000 blocks per second. This is evident when using the new MCA generator, probably less with the MCAFilter if doing anything complex, and significantly less whenever you are doing sequential single block changes.

If you aren't a programmer, you can use some aspects of the generator with PlotSquared installed. Early demo:
(I've since added caves/ores/schem population)

I've also added the `/2 replaceall` command, which is applicable if you are using PlotSquared's `enabled-components.worlds`. (needs the latest P2)
