*: update... this commit: 1. consolidates dark theme stuff to dark_theme.cpp 2. creates a new widgets folder to store all of our custom widgets 3. creates the list settings page in the information dialog, although much of it is nonfunctional: it doesn't save, and the status doesn't even get filled in... we'll fix this later!
