- recently restored sequencer change data operator didnt reset the offsets after a hard cut, causing the new data to be trimmed.

- add change data operator to strip panel next to image file properties since editing every image manually isnt really usable.
- added new sequencer operator "Clear Offsets" (Alt+O), useful to reset the start/end frames around the strip data.
