Subject: [PATCH] build.sh: Rework branch concept

We only build "stable" images now and push them first to the testing
branch and then to the stable branch. Thus, the versioning should always
be based on the newer of the two branches, stable and testing. A
paramter isn't needed anymore.

This closes #15 and #14.
