List existing node groups in 'Group' categories for easy instancing.

This includes polling by type and recursion level to ensure groups
are only added in appropriate tree types, and don't create cyclic
dependencies.

Poll node groups based on node tree datablocks rather than node instances.

There is a redundancy in the nodetree/node relationship, since each nodes
is part of exactly one node tree. This means we can test for either trees
or nodes to detect cycles, and because we usually poll for node trees
rather than nodes that would be the natural choice.

Automatically create a new node tree when making an object component node.

Use inheritance for widgets

And of course minor cleanup

Create a default minimal node setup when creating new trees or groups.

Refactor widget library

* Rename folder 3d_widgets/ to widget_library/
* Split up wm_generic_widgets.c into separate .cc files for each widget, move them into widget_library/
* Rename files containing geometry vectors from xxx_widget.c to geom_xxx_widget.cc
* Rename wm_widget_library.h to widget_geometry.h (contains the geom_xxx_widget.cc declarations)
* Add widget_library.h (contains widget library API declarations for external access)
* Move widget drawing function to wm_widget.cc
* Add/improve (doxygen) comments
* Remove wm_generic_widgets.c
* Usual cleanup

We have 22 files for widgets now :S Seems a lot, but maaaaaan things are so nicely structured now!

Fix incorrect file names in doxygen comments

Changed file extensions in rBbaca87c20cc22

Correction to previous correction

Forgot to use 'git add'. Sry for the noise.

Corrections to previous commit

Forgot to move wm_generic_widgets.c to the new place and to correct paths in doxygen comments

Move widget files to a proper place

readme updates

Cleanup: Remove C version of widget-map, unneeded struct declarations

Merge remote-tracking branch 'github/soc-2014-fluid' into soc-2014-fluid

cleanup from previous noise test

PRB viewport : Adding lamp support and post effects. and lots of gpu stuff.

Cleanup: Move around enums & declarations, comments, ...
