changes to allow the status line to be entirely configured with a single option. Now that it is possible to configure their content, enable the existing code that lets the status line be multiple lines in height. The status option can now take a value of 2, 3, 4 or 5 (as well as the previous on or off) to configure more than one line. The new status-format array option configures the format of each line, the default just references the existing status-* options, although some of the more obscure status options may be eliminated in time. Additions to the #[] syntax are: "align" to specify alignment (left, centre, right), "list" for the window list and "range" to configure ranges of text for the mouse bindings. The "align" keyword can also be used to specify alignment of entries in tree mode and the pane status lines.
