Functionally implement the creation/finishing of release branches.

TODO.mdown

 TODO-list
 =========
+
+General configuration
+---------------------
 - Support configurable naming for fixed branch names 'master' and 'develop'
 - Support configurable naming conventions (i.e. name prefixes) for supporting
   branches, instead of fixed 'release-\*' and 'hotfix-\*'
+
+Release branch support
+----------------------
+- Take care of the situation where two release branches live next to each
+  other. In that situation, a "finish release" action should merge back changes
+  into the other release, not into 'develop'. Or at least warn about it. Or not
+  support creating a new release branch if the other isn't finished yet.
