This commit adds a test case, which makes sure that the KDE framework
and plasma framework version are always the same.
Additional changes:
* APKBUILD parser parses the URL now (that's the best way I found to
categorize the KDE aports in frameworks and other)
* Changed single quotes to double quotes in KDE APKBUILDs, so the
parser doesn't include the single quotes in the parsed result
* Added the test case to the gitlab CI config
* Add NetworkManager and PulseAudio applets to Plasma
* This crashes plasma mobile on armhf (where it is not usable due
to performance problems anyway), except on mainlined kernels
with hardware accelerated graphics. This is mentioned in the
pkgdesc of postmarketos-ui-plasma-mobile now.
