Sculpt/2.5:

* Added toolbar UI for setting "anchored" mode
* Added a "persistent" mode for the layer brush; basically you can keep sculpting on the same layer between strokes when this is on. There's a button to reset the base so you can add another layer on top of that, and so on.
This feature was suggested by Blenderer on BA, thanks!

Note, I think these options could use better names in the UI, but I couldn't really think of anything very descriptive, suggestions welcome
