Previously, the current request would just get a new EditSession when
one was created. Now, a Request is reset before and after:
- a command is used and
- an interact is fired with the platform
This means each action taken will get a single, non-reusable Request.
Note that this only applies to actions taken through the platform.
API users will not be using requests anyway, since things like Masks,
etc. will be constructed directly instead of being passed through the
platform's parsers and so on. (e.g. if a plugin loads a schematic into
the world with a mask, they should create the EditSession and mask it
directly, and not use that Mask again for another EditSession in another
World).
Also, get rid of a bunch of (some now-)unnecessary EditSession creation
during command dispatching.
Note that this also fixed the dynamic selection mask, which apparently
has been broken for some unknown amount of time.
For example, if you set a mask that takes an extent (many of them),
and then move to another world, the mask will test blocks in the old
world and return bad results.
Instead of trying to maintain a list of "natural terrain blocks", just
let the user specify a mask of blocks to use for the height map filter.

- Move Vector, etc. into `.math` package
- Drop many methods that will be auto-promoted anyways, eg. with
`divide(int)` and `divide(double)` the first is now gone.
- Take Block vectors into their own class hierarchy
- Make it clear throughout the API what takes blockvectors
- many more improvements
