LBCORE-1006 Remote CMT versions and set install_project tags from git

First test with version/tag substitution in install project. format "%d" prints more than we want, and I couldn't get %D to work.

We could also have a python script do the replacement based on the output of git describe.

One missing functionality is the creation of LbLogin.sh (done in build/post-config I suppose).

Fixes LBCORE-1006

According to git log --help on lxplus, %D is not supported in the version of git we use.
