mode7: use roi instead of imagesize only

I already sent this to the mailinglist but i was told to post it here.

We patched the dc1394 plugin in order to use 
dc1394_format7_set_roi() instead of dc1394_format7_set_image_size()
and added the roi_top, roi_left to the caps.

with this modification it is possible to set the format 7 
window size AND the position of the window.

Example: 
- the camera can grab in 1280x768
- set window size to 640x480
- set roi_left=200, roi_top=200
-> the camera will grab the 640x480 region starting at 200,200

If the roi_* caps are not given, the window will be sampled at 0,0
