Enhancement request: Update UGUI to support latest Bootswatch #14
Description
I believe UGUI currently uses Bootstrap 3/older Bootswatch themes. These have some grid text vertical alignment issues by default and don't have all the modern bells and whistles like button-style radio selection.
This is a request to enhance UGUI to support the latest iteration of the Bootswatch themes, ex. https://bootswatch.com/cerulean
(I've messed with implementing the latest Bootswatch Cerulean myself, but what I've tried breaks the UGUI navbar, etc.)
