Problem

The command rose stem does not work if the suite was checked out from a git repository instead of SVN. To minimise immediate porting work in the context of the UKMO git migration project, I am adding 'minimal' git support, i.e. just enough to avoid an abort.

Long term new keywords might need to be added to fcm keyword (e.g. jules.git.xm, ...)? But I'll leave that for the UKMO to decide.

Proposed Solution

• fcm loc-layout aborts. Implement git-aware version of _ascertain_project that tests for the existence a .git directory, and if so, deduce a project name etc from git
