== Sequencer ==

Moved status info bar into panels. It was always shown on the wrong place...
Added anim-startofs and anim-endofs, so that one can specify the range of 
_input_ that should be used. 

There is a subtle difference to start-ofs and end-ofs,
which will show, when you use "Reverse Frames" or "Speed Control". Both
effects operate on the input-range and _not_ on the display range! Now
you can control both in a comfortable way. Only thing missing: a button
to copy start-ofs and end-ofs to anim-startofs and anim-endofs.
(Andy: that was the feature you missed, when storyboarding with the sequencer
and the speed control effect :)

Also: added File-Name and Dir-Name to redirect input as needed.
