Changes to Brush texture workflow

This changes how textures are accessed from Brushes, with the intention of simplifying 
the workflow, and reducing the amount of clicking. Rather than the previous texture slots 
(which didn't work as a stack anyway), brushes now have a single texture linked. Rather 
than taking time having to set up your slots in advance, you can now select and change 
textures directly as you sculpt/paint on the fly. For complex brushes, node textures can 
be used, or for fast access, it's easy to make a duplicate of your brush with the texture 
you like and assign a hotkey.

Brush textures can now be chosen from a new Textures panel in the brush tool 
properties - click on the thumbnail to open a texture selector. This is done using a new 
variation on the ID template - the number of rows and columns to display in the popup 
can be customised in the UI scripts.
