Nicholas Marriott 1f8256fc50 Drop having a separate type for style options and make them all strings, which
allows formats to be expanded. Any styles without a '#{' are still validated
when they are set but any with a '#{' are not. Formats are not expanded
usefully in many cases yet, that will be changed later.

To make this work, a few other changes:

- set-option -a with a style option automatically appends a ",".

- OSC 10 and 11 don't set the window-style option anymore, instead the fg and
  bg are stored in the pane struct and act as the defaults that can be
  overridden by window-style.

- status-fg and -bg now override status-style instead of trying to keep them in
  sync.
