gst-element-maker: add video pad template and use it in videofilter class

Browse source 
Would be nicer if one could just supplement the generic template
from the element template though.

Also, I would really have liked to just add those sections from the
pads template into the element templet directly (so I can cater for
src template caps == sink template caps), but that didn't seem to
work.
