Feature to avoid the modification of project version automatically if version is not explicitly set to 0.

[xeagle2]

In some of the scenarios with multi module projects some of the sub module projects have to keep the fixed version, for example if the module is an enhanced version of specific third party library, etc and if the whole project is triggered to be build it's not necessary to replace the versions across all projects.

Therefore it would be great to replace the version for projects where the version explicitly set to 0, or not declared like for .

Thank you,
