Orange:

For some ancient reason, the stride option only worked on a single strip,
and extended always. This made it nearly impossible to integrate it well
with other actions in NLA.
This commit changes it as follows;

- As any strip, the striding-strip also stops at the end of a strip
- This allows to put multiple different actions on a single path, and if
all of these have the striding option set, the actions will each do their
own individual stride.
- To match the different actions, a new "Action Offset" button was added
in the NLA Panel, which allows to internally cycle the action.
- Of course, blend-in and blend-out works nicely too.

Here's a quick AVI test with 2 actions. There's some slipping of the feet
between actions still, because of the stridebone blending. I might look
at that later, for now you can correct it with a simple Ipo on Armature too
