Bootstrap 4 Update

Created by: Tampa

Bootstrap 4 has been released, however the changes in it require various parts of the template to be updated along with fixing and updating various dependencies. First attempts at an update for Bootstrap 4 were less fruitful.

It would appear that while the basic theme changes are easy to do, the entire popup system does not work under Bootstrap 4. I do not know why that is. Updating magnific-popup to its latest version does not yield any improvement either. Popups continue to refuse no matter what.
