grass.py: used space as delimiter to get GRASS_VERSION_STRING (#405)

* use space delimiter for GIS_H_VERSION

* choose GRASS_VERSION_STRING list element

* report header version and date

* write GRASS_VERSION_GIT to grass.py

* use GRASS_VERSION_GIT

* write GRASS_VERSION_GIT to grass.py

* fix tab indent

* add date

* add date

* get date correctly after #325

* get date correctly after #325
