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
This makes debugging much easier, because the relevant log messages
before the crash can always be found at the bottom of the log files,
and not somewhere in the middle.
