Blender Git Loki

3ds_export - enabled textures as an option since it works with some appliactions (only way to get textured models from blender to google sketchup)
3ds_import - added option to disable recursive image searching (could be slow somtimes)
export_obj - when making group/object names only use both object and mesh name when they differ.
weightpaint_clean, weightpaint_grow_shrink - minor updates.
Render.py - own error in epydocs.
