[GRASS-dev] [grass.script.core] parser() casts options as strings

would make sense to change it in GRASS 7, e.g. option->answer as
'union' (int, double, char *). In this regard also check given value
by the parser. Then the parser could print a warning when the user
enter option value which cannot be casted to the given data type (e.g.
string for integer option).
