Subject: [PATCH] Add colorscheme switching and airline/tmux autoset

Use <leader><F8> to set a new colorscheme in vim. The airline
automatically sets itself to the corresponding colorscheme, as does the
tmux statusbar at the bottom.

Use <F8> to toggle between dark and light mode for the colorscheme (not
all colorschemes support this unfortunately, I might restrict the
installed colorschemes to those that do). Again, Airline and tmuxline
will automatically adjust themselves.

Tmux prefix highlight plugin has been removed, since its functionality
can be replicated easily with the ?client_prefix function in tmux -
which also works regardless of any styles applied to the statusbar
through tmuxline. Currently, whenever the prefix is active the
clock-area will turn bright blue.
