Fix the following whitespace formatting issues:
- Indentation in scdoc source files should be done with tabs.
- Lines where there (clearly) should be a line break, need to have '++'
at the end, but several were missing them.
- The scdoc manual (clearly) states that lines should be hard wrapped
at 80 columns, but when line(s) are indented, that causes rendering
issues. So lines where a line break was not clearly intended or
clearly not intended, have been put onto 1 line to circumvent the
rendering issue.

Provides CSS classes empty, floating, tabbed, tiled, solo, stacked and
app_id.
Adds offscreen-css bool option (default false), only effective when
"all-outputs" is true. This adds styles on outputs without focused
node, according to its focused workspaces window situation.
Adds an "offscreen-css-text" string option (default empty), only
effective when "all-outputs" and "offscreen-style" are set. This
is shown as a text on outputs without a focused node.
Adds a "show-focused-workspace" bool option (default false) to indicate
the workspace name if the whole workspace is focused when nodes are
also present. If not set, empty text is shown, but css classes
according to nodes in the workspace are still applied.
Limitation:
When the top level layout changes, there is no sway event so the
module cannot react. Perhaps in the future recurring polling can
be added to go around this limitation.
