Added a few new things using block states.

Browse Source 
* `//set ##*tag` sets all states in the tag (not just default state per type)
* `//set ^type` is a pattern changing block type but copying all valid existing states
* `//set ^[prop=val,...]` sets the property `prop` to `val` wherever the existing block has that property
* `//set ^type[prop=val,...]` does both of the above
Those work anywhere a pattern is taken, of course.

* The mask syntax `^[prop=val]` matches blocks with the property `prop` set to `val`, or blocks that don't have the property at all.
* The mask syntax `^=[prop=val]` only matches blocks that have the property.
Those work anywhere a mask is taken, of course. (`//mask`, `//gmask`, `//replace`, etc)

The `//drain` command now takes `-w` flag that removes the waterlogged state from blocks (in addition to removing water, as before).
