NLA SoC: Tweaks from feedback from Broken + jez

* Renamed the 'blend' blending mode to 'replace', since that's what it usually does

* Drawing a darkened rect behind the keyframes shown in the action line

--

* Fixed typo made last night which broke compiling
* Consolidated all the keyframe-shape drawing code to use a single codebase. Even if we don't ultimately go with OpenGL keyframes, there's always a tidy option for that now.
