ISO for 2015-05-08

# changes
- kamoso integrating (sudo apt install kamoso) - presently broken
because I think the qtgstreamer build is garbage
- dragon integrating (installed by default)
- the ISO is built using the daily snapshot PPA again
-- bluedevil is no longer available for installation (it wasn't
installable anyway due to missing bluez5). it will remain so until
bluez5 lands in kubuntu (which might well be never considering how
long we've been waiting ........)
-- daily snapshots have a bunch more automated QA applied to them to
increase overall snapshot reliability

# errata
- kamoso busted because of what appears to be a missing gstreamer plugin
- installer window decoration uses !breeze colors. fix discussed;
needs implementation in the installer code itself.

# random kubuntu CI notes
- kubuntu 14.10 support is ending [1]
- kubuntu 15.10 support is starting shortly [1]
- ISO foundation will switch from 15.04 to 15.10 as soon as initial
integration is set up
- automated qml runtime dependency QA has been expanded to cover more
repositories, following some performance improvements to do with
docker having mental defaults
