Merge branch 'master' into app-templates

Merge branch 'master' into app-templates

Cleanup: style

Missed adding this previous commit

Include classes to filter as a callback

Move AppOverrideState into a helpers submodule

Split out override class into its own base class

This means multiple templates can share a single base class,
each templates class only needs to fill in the callbacks.

Hide most panels in the NKey 3d view region

Merge branch 'master' into app-templates

Fix for new-file removing template

Add back basic panels for 101 making it more usable

Remove underscore blecklist/whitelist

Correct missing text argument for label

Fix for preset menus

Initial commit: Replaces bvh function to snap nearest.

BVHtree to snap to vertices and edges is independent of ray. The function for previous transverse was unclear and not very efficient.
The function used now, projects four vertices of aabb to test if it is within the threshold.
It still needs to optimize even more (prioritize axis, anticipate return)

I'll still test the optimization

Datablock ID Properties

Summary:
The absence of datablock properties "will certainly be resolved soon as the need for them is becoming obvious" said the [[http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.67/Python_Nodes|Python Nodes release notes]]. So this patch allows Python scripts to create ID Properties which reference datablocks.
This functionality is implemented for `PointerProperty` and now such properties can be created with Python.

In addition to the standard update callback, `PointerProperty` can have a `poll` callback (standard RNA) which is useful for search menus. For details see the test included in this patch.
