Continuing on from my previous 'Expandable/Collapsable Action Channel' commit, this commit introduces the ability to show/hide the keyframes in each ipo-curve represented by an Action Channel.
When you expand an Action-Channel by clicking on the triangle beside its name, you will now be presented with options to show/hide the ipo-curves represented by
the Action-Channel, and/or the Constraint Channels belonging to that Action-Channel. Actual ipo-curves will not be drawn in the Action-Editor, but the keyframes
will be shown.

Possibly Coming Soon/Further Work:
* 'Protection' options for ipo-curves (currently disabled in code, as all IPO-related
tools will need to be made aware of this)
* Sliders for IPO-Curve Channels of the active Action-Channel
