Title: added an option to check the destination branch's last commit, and rebuild

... if the destination branch has changed. This is useful if you are merging your Pull Request source branch into the destination branch before building.

update documentation with instructions about merging before build, and to mention "Rebuild if destination branch changes?" checkbox
