Some minor adjustments.
Plugins [Pike-GitLab]: Improved handling of labels.
Plugins [GitLab]: Report issue changes from update_issue(). Issue alterations are now reported.
Plugins: Added flag to check_commit() to inhibit changes. The check_commit() plugin hook is now called also from CommitHookUtilsRepo::check_commit().
Plugins [Pike-GitLab]: Add support for the label "To Do: Testsuite".
Plugins [Pike-GitLab]: Only switch to existing controlling branches. Currently there exists a milestone "Pike 9.0", but the branch "9.0" has not yet been split from the master branch, so the master branch should remain being the controlling branch for those issues for now.
Plugins [Pike-GitLab]: Fixed label filtering. The argument order to glob() was reversed, causing the labels to not be detected as intended. Also added display of any remaining To Do:-labels.
Plugins [Pike-GitLab]: Add support for old YouTrack PIKE-XXX issues.
Plugin (Pike GitLab): Fixed typo in label name.
Plugins [GitLab-Pike]: Fixed milestone check.
Added pike-gitlab plugin.
