[kdenlive] development synchronization

[Steve Guilford]

Greeting JB.

Thanks for the update on the status of the KF5 port.  I concur w/ your plan.

Regarding MLT and QT5, Dan's Shotcut video editor is running w/ the QT5 
branch.  I have a copy of Shotcut running on my Ubuntu 14.04 LTS 
workstation - which has both QT4 and QT5 installed.  Most of the MLT 
code avoids QT and he's already done the work to make it compile w/ QT5.
