Blender Git Loki

Added icons for outliner display of Modifiers. Used ones as provided by
Eckhard Jaeger on forums. http://download.blender.org/demo/test/rt9.jpg

Notes;
- made new Armature icon, based on looks of Action icon. Using a Bone icon
for everything was too confusing
- made softbody icon softer... it looked like a water drop, something that
would be better for Fluid stuff later :)
- the Modifier icon itself (wrench) looks a bit too much like a tool... but
its a clear icon that stands out.
