Refactoring App Image

[Harald Albrecht]

Hi,

just  gave the refactoring branch AppImage a try on my Kubuntu 16.10 and 
tried to load my existing projects (hm, Devil's advocate, probably) ... 
but that didn't work quite the way I expected; wasn't there some note 
about (not) importing old projects? ;) Most project bin clips don't turn 
up and the timeline is very, erm, minimalist upon trying to load an 
existing project. :)

So I toyed a little around using some clips. One thing I noticed is that 
right after start the tracks are "normalized" (for lack of a better 
term), but don't show the control buttons for no-audio, no-video, 
locked. Only after minimizing them and normalizing them again the 
buttons show up for me.

At start the timeline seems to default to some initial default length 
about 10mins or so?

Alas, it's good to see that there are now AppImages coming so we can 
play around with them. Many, many thanks for all the hard work spent on 
refactoring to bring Kdenlive to this point!

Best regards,
Harald
