Factories are now on NCPPlugin level, thus all the core stuff can be in
one module, giving better source code browsing.
Updates has been moved into an updates package, because there is to be
expected more content, and to make utilities less fat.
To indicate the direction, the basic infra-structure has been added to
allow adding components to the DefaultComponentFactory. Further
processQueuedSubComponents is now called after each components adding in
order to allow more flexible registry features.
* This method is "hard-coded" and not configurable yet.
* Prevent throwing and teleporting into blocks directly, prevent
the second throw on glitching into a one thick ceiling (might lead to
lots of passable violations at present).
* If stuck in a block with the feet (not sand/gravel) without being on
ground, throwing is prevented.
* Some dependencies were updated, hopefully without conflicts for
backwards compatibility (untested).
