start of add object framework. mainly a copy from add_object_utils.py plus some convenience functions atm. when in a more robust state discuss with ideasman if to remove add_object_utils.py

discussion over naming conventions

... and renaming it. Not sure system is valid 100%, also "object" was tempting but object is used for objects in 3d view eh...
Need to talk about this, maybe it will be more clear after testscreenings will have done the add object framework (we'll move stuff anyway).

Moving to category System, after seeing the video from Colin Levy it's clear this is usable in many places, didn't know about it!

Looking at the code seems like this addon could be expanded to more spaces than 3dview and sequencer...

nazg-gul it is stable now!

draw functions cant edit scene data now, these values are set in execute() so should not be set while drawing the menu.

exploded" and "it's the single most bright point in the universe"

Added automatic external data packing to avoid problems where the user submits a session without textures

- committing this in behalf of jahka, is kinda busy :)
- I'm going to commit some changes but this is the version found in the tracker, this way my changes will be easier to track

- moved the conditions Obj.type == 'CURVE' in poll methods
- general formatting

* Applied patch by Filiciss Muhgue that (mostly) fixes the quad view. Thanks for that!
* Patch link: https://projects.blender.org/tracker/?func=detail&atid=127&aid=24932&group_id=9
* TODO: Make Quad view more useful (fix text position, display 2D value of the hypotenuse rather than the 3D one)

- solved the problem I had with this addon, finally
  the addon was saving the blend as it is and in my case a compressed blend file was giving problem when played in the runtime

- hence added a bit to manage compressed blends to embedd them uncompressed

  NOTE: this should be fixed in the player itself I think, same says campbell, but worth checking

- now moved to trunk :)
