Merge with trunk
[ Sebastien Bacher ]
* [hospot] include cmakefile hack to get files listed in qtcreator
* [security-privacy] use the system location as well to look for trust
store items, that's needed at least for unity8-dash which is not
distributed as a click and doesn't a .local entry (LP: #1501428)
* [sound] don't display silent mode warnings, sounds should just be
played when user selected (LP: #1391502)
[ jonas-drange ]
* [phone] encode numbers before passing them to url-dispatcher (LP:
#1496845)
