More travis-ci tuning

Let's be a bit more sane with the paths. There is no need for tons of
relative cd'ing, just go to the repo folder before proceeding with cmake
shenanigans.
Path fixes
Merge remote-tracking branch 'origin/master' into coverity_scan

Conflicts:
	.travis.yml
Merge remote-tracking branch 'origin/master' into coverity_scan
Merge remote-tracking branch 'origin/master' into coverity_scan
Merge remote-tracking branch 'origin/master' into coverity_scan
Merge branch 'master' into coverity_scan
Merge remote-tracking branch 'origin/master' into coverity_scan
Merge branch 'coverity_scan' of https://github.com/daehlith/QtGoogleAnalytics into coverity_scan
Let's see if the repo rename was the problem.
