Currently we have a python file for styling and configuring the UI - arches_project/core/views/stylesheets.py.
I think this should change to a directory (arches_project/core/views/stylesheets/) which can contain two files arches.py and default.py. This will allow for a correct separation of the two, and make it easier for additional styles to be introduced in the future.

In addition, I think the current checkbox for toggling the Arches styling on/off should be replaced with a dropdown which still defaults to the Arches styling.
