Alright, got bootstrap working
Themes working as well
Checkboxes also up
Counter moved into dropdown menu
Settings will always hide with settings, but there's an extra close button for those playing not centered
Doesn't save settings (yet)
TimeKeeper still needs a new complete copy menu, and it's own checkbox
