NLA SoC: Basic Strip drawing
Implemented some basic strip-drawing code with some hardcoded colours. These colours will be made into theme colours at some point, but the aim is to use different colours as indicators of the 'state' of the strip (i.e. active/being tweaked, uses the same action as the strip being tweaked, selected, normal).
This is not yet usable though...
