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.
Moving big parts of code between sub-projects. Some refactoring was
needed to unlink some classes. Deprecated methods removed. Some utility
methods were moved to differently named utilities. Few signatures
changed (e.g. BlockProperties.init). Most changes should only concern
bugs or developers who dug into some NCP deeply (not sure those exist).
It should still all be there.
