Add a send amp's gain control as a send controllable.

Tweak AutomationControl now that PBD::Controllable has
a default implementation of user_to_ui and ui_to_user. 
Add correct implementations of these methods to
Amp::GainControl.  Hence allow SendProcessorEntry to
use the generic mini-fader-adding code from
ProcessorEntry.
