GUI: Included Mapvalidator in forms.py to check valid raster output names

[bluedotblue]

Description

Within the GUI, creating new raster maps with a required output name does not prompt the user of invalid character use on running the module. This feature has been applied already when creating a new vector map, with the MapValidator class within widgets.py. It was asked to use this MapValidator class to handle raster output names similarly in forms.py.

This pull request addresses issue #5978.

How has this been tested?

I overwrote the installation forms.py with my version and ran the GUI to check visually.

Thank you! It looks like it's preventing the dialog from running even if the name is correct.

Looking back at the linked issue, I would go with a different approach more consistent with the current usage of validators in the tool dialogs, e.g. see how r.surf.fractal dialog deals with entering some letters instead of numbers in the dimension parameter - it will highlight the field.

For that you need a slightly different validator, something like this would work (in gui_core/widgets.py):

class MapNameValidator(BaseValidator):
    """Validator for map name input"""

    def __init__(self):
        BaseValidator.__init__(self)
        
    def _validate(self, win):
        """Validate input"""
        text = win.GetValue()
        if text:
            if not grass.legal_name(text):
                self._notvalid()
                return False

        self._valid()
        return True

    def Clone(self):
        """Clone validator"""
        return MapNameValidator()

and then you just add it to
