3D Audio GSoC:

Adds new speaker object type.

Notes:
* Needs some nice icons
* Quickily review by Joshua Leung (5 mins)
* Properties UI updated (with help of Thomans Dinges)
* Speakers have their own theme color
* No real audio functionality yet.
* Minor bug regarding lamps/lattices fixed in interface_templates.c

I personality tested:
* Creation, Deletion, Duplication
* Saving, Loading
* Library linking (incl. make local)
* Tracking
* Dope Sheet, Outliner
* Animation
* Drawing (incl. Theme)
