Parsing error due to tabs in config file

[tasmin]

When I create a bare repo and push from GitExtensions into it, the config file has tabs in it. GitStack throws parsing error when there are tabs in the config file. Sometimes the page does not work, for example, click on the users icon for a rep, it shows no users, and Add User dialog lists no users. Some other pages show this error: File contains parsing errors: ...

This can be fixed by adding the 2nd line in python/lib/ConfigParser.py for defining OPTCRE:

    OPTCRE = re.compile(
        r'\s*'                                # ignore any starting white space [by Tasmin]

Looks like OPTCRE_NV should have the same fix:

    OPTCRE_NV = re.compile(
        r'\s*'                                # ignore any starting white space [by Tasmin]
