Cycles: add location/rotate/scale and XYZ mapping options for all texture nodes, to reduce the amount of nodes needed to set up a simple texture. These are currently editable in the texture properties tab, still need to make them available in the node editor. Projection and color modification options will be added later, they're not implemented yet but allocated already to avoid version patches later. Also an issue with the XYZ mapping is that when you set one to None, texture and material draw mode doesn't draw the image texture well, OpenGL doesn't seem to like the degenerate texture matrix?

Cycles: tweaks to properties and nodes * Passes renamed to samples * Camera lens radius renamed to aperature size/blades/rotation * Glass and fresnel nodes input is now index of refraction * Glossy and velvet fresnel socket removed * Mix/add closure node renamed to mix/add shader node * Blend weight node added for shader mixing weights There is some version patching code for reading existing files, but it's not perfect, so shaders may work a bit different.

Cycles: procedural texture nodes reorganization. This will break existing files using them, but rather do it now that I have the chance still. Highlights: * Wood and Marble merged into a single Wave texture * Clouds + Distorted Noise merged into new Noise node * Blend renamed to Gradient * Stucci removed, was mostly useful for old bump * Noise removed, will come back later, didn't actually work yet * Depth setting is now Detail socket, which accepts float values * Scale socket instead of Size socket http://wiki.blender.org/index.php/Doc:2.6/Manual/Render/Cycles/Nodes/Textures
