NLA Transform Bugfixes:

Browse Source 
* Scaling NLA-strips now resets their scale setting correctly at all times
* Added safe-guards against negative scaling being created through the use of the transform tools.

Note: at scale 0 or thereabouts, there will still be a little blip, when keyframes are scaled as if scale were 1.0f. It's quite harmless.
