fix: get the correct Git version for the project
The ::fwfwk::getVersion procedure is called for each namespace and puts version information into variables within that namespace (VerMajor, VerMinor and so on).
The ReleaseName variable is contructed from VerString in the ::fwfwk namespace, but this contained the Git version for fwk, not the project.
Treat the ::fwfwk namespace specially by finding the ProjectPath variable which only ::fwfwk is supposed to have.
