Feature request: Make the Froala Editor deactivatable

[mpibpc-mroose]

I'm a fan of behavior testing using Splinter which bases on Selenium. The problem with a FroalaField in those tests is, that they are not rendered as form fields and so they can not get filled by the default Selenium/Splinter methods. So I would like to be able do deactivate the FroalaEditor when running those tests using settings.py.

As a proof of concept I implemented this as follows:

from django.conf import settings
from froala_editor.fields import FroalaField
from django.forms.widgets import Textarea

class DeactivatableFroalaField(FroalaField):
    """
    FroalaField which allows to disable the FroalaEditor widget
    using settings.py's variable USE_FROALA_EDITOR
    """
    def formfield(self, **kwargs):
        try:
            use_froala_editor = settings.USE_FROALA_EDITOR
        except AttributeError:
            use_froala_editor = True

        if use_froala_editor is False:
            # disable the Froala Editor by just
            # rendering a Textarea
            defaults = {
                'widget': Textarea()
            }
            defaults.update(kwargs)

            return super(DeactivatableFroalaField, self).formfield(**defaults)
        else:
            # leave as it is
            return super(DeactivatableFroalaField, self).formfield(**kwargs)

As this is quite useful for me, I kindly ask the developers to "incorporate" this idea into the code base.
