2.5: startup.blend changes, these should all be consistent with new datablocks,
mostly the startup.blend was trailing behind. Also renamed B.blend.c.

* Lamp shadow buffer was Classical instead of Classical Halfway.
* Point Lamp was named "Spot".
* Render resolution is 50% 1080p.
* Scene and material bake/use tangent space normal maps.
* Remove empty text datablock.
* Enable auto ray bias on material.
* Change default material diffuse color to match new material.
* Mist start/depth from 0/0 to 5/25 so it does something.
* AO uses Add instead of Multiply.
* Change world colors for new world same as startup.blend.
* Default cube rotation was 0,-0,0 now 0,0,0.
* Enable relative/filter/hide files in user preferences.
