Awesome stuff, Vincent! Appreciate the time you've taken to set all of 
this up.

One comment: I did a poll on the Ubuntu G+ community, asking users 
whether they use the LTS ubuntu releases or the non-LTS. So far, over 
1,090 people have voted, and a STAGGERING 71% use LTS releases on their 
primary machines 
(https://plus.google.com/+JesseDuBordFilms/posts/3VkkxrzCzZV). I might 
encourage support for the latest LTS release for Kdenlive PPA's, in 
both the new timeline ppa and the master ppa (seems like LTS support is 
already in stable ppa). Having packages for those LTS versions would 
expand the use of them, drastically, based on my findings.
