injectAllReactorProjects overwrites non-git properties in reactor projects

[tnaroska]

The option injectAllReactorProjects should set the git-commit-id related properties in all reactor projects. Right now the code does not only propagate the git properties, but all properties set in the current project (i.e. in the pom.xml's element).
This can overwrite properties completely unrelated to git in other projects leading to unexpected behavior.

Today I started to use the maven-git-commit-id-plugin and I ran into the same issue :(
The only workaround is:
false

This is a problem e.g. with the maven-scr-plugin and the maven-bundle-plugin, because they communicate via properties. If those properties are propagated across module boundaries this leads to all kind of errors.
