Sequencer: (small Durian wish)

* new operator: set rendersize (SEQUENCE_OT_rendersize) sets the render output size in the current scene to the size of the active sequence strip
* works for movies and images right now
* TODO: currently only works if image or movie strip has been loaded (as in showing the preview for example) - reason is that otherwise the size is not initialized in the strip
