Subject: 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.
