Merge branch 'master' of github.com:github/github-services into improve-xmpp-filter-branch
Improve branch filtering and add test
Updated as suggested
The default behaviour of 'Always running a build' (with the add2Queue parameter) is not always desirable, because some TeamCity setups can have carefully configured rules about when to actually do a build which are ignored by this direct approach. This commit adds the option to just poke the TeamCity instance to check for changes (effectively the same as hitting the 'Check for pending changes' option in the TeamCity web user interface), which allows any TC build-rules to be applied.

The checkForChangesBuildType parameter is not well documented, but it is directly referenced by a JetBrains employee Yegor Yarko here:
