Short description of error
Cyclic Strip Time not work with Action Clip

Exact steps for others to reproduce the error
I attached .blend to show this bug.
The track called "Ok" works with the "Cyclic Strip Time" check mark correctly.
The track called "Bug" works with the "Cyclic Strip Time" check mark incorrectly.

In the track "Ok", there are two keys, at 0 and 10 frames.
In the track "Bug", the same two keys, but for 43 and 53 frames. In the Action Clip, I set the values Frame Start =43 and End = 53.
I expect that the "Bug" track will perform the same actions as the "Ok" track, but this does not happen.
I think this is a mistake.

Can confirm basically for all cases where strip->actstart is non zero.
I'd say this is broken by design, since fmod then gives you strip time outside of specified Start / End (can give you negative strip time even) and thus evaluates to zero outside that range.

Other issues with it:

evaluated result is not represented in Strip Time (as opposed to fmodifiers, their result is shown in the UI)
Cyclic Strip Time should be in the Animated Strip Time subpanel (or at least be greyed out when Animated Strip Time is disabled)
