  pythonlib: return None from run_command() (#165)

Removing the 7.0.0 backwards compatibility from run_command()
which was raising exception on error but returning 0 on success.

Adding option to use the standard fatal() error handling
which might be good for use within GRASS GIS code itself.

Adding extensive documentation for the available options
and linking all relevant functions.

Also passing module name explicitelly to CalledModuleError
as a parameter.
