WIP: fancier tab bar

Browse Source 
`use_fancy_tab_bar` switches to an alternate rendering of the tab
bar that uses the window_frame config to get a proportional
title font to use to render tabs, as well as rendering a few
additional elements to space out and make the tabs feel more
like tabs.

Computing the number of tabs doesn't respect the alternate font
at this time.

Formatted tab item foreground and background colors are also
not respected at this time.
