First shading steps: actors and scene are drawn with shaders.
Actor z-ordering in render
VaoBase: cleanup at deletion, const correct methods
Add a valid property to modelvalues
Don't reset the camera when tha player dies
Texcombiner: now different sized sprites are acceptable for the same actor
New actor class: pickup introduced, picking up weapons is now possible.
Some common functionality moved from PlasmaGun to Weapon
Finished the opengl3.3 transition; using core profile, rendering is done purely in shaders now (changed: particles, ui).
App side support for the latest texcombiner changes.
Cleanup in renderer, actor rendering moved to own class.
Drop the empty body_*_actions, now a single action can have multiple sprites rendered.
