reorganize tests:
all story component code now is supposed to deal only with products of FragmentComponent.resizeFragment()
rearrange fragment processing:
1. resize fragments
2. make fragments black+white
3. rotate if needed

also, a video information dump is saved for all uploaded fragments, which should make future debugging more interesting

consequently, story processing no longer involves blackandwhitening, only watermarking is performed

tests changed accordingly

hopefully fix #11 and fix #1 finally ,)

It should be noted, that currently video processing drops frames on some weirder frame rates (8, 14, etc). Please adjust handset video frame rate to something most possibly common.
some last minute fixes
