Various fixes so sculpt_init_tool_override_channels
for shift-smooth can replicate the prior behavior:
* Brush spacing will now look up brush channel
spacing directly for sculpt, instead of relying
on copying the channel data into Brush.
* Brush spacing code will now use brush channel
pressure for sculpt. Fixes broken shift-smooth
pen pressure.
* The falloff_curve channel is now automatically
added (before it was only used internally by
command lists, the code was defaulting to
the Brush field otherwise).
* BrushCurve now has an option for custom curve
presets to have negative slopes.
* The Falloff panel now puts the type dropbox
inside the panel header.
* Falloff panel also now uses brush channel data in
sculpt mode.
* falloff_shape is now a brush channel
In a somewhat unrelated change, I also unnested the
Brush Settings subpanels. It's been driving me
insane for a very, very long time. Much more
usable this way.
