Fix hotkey functionality. 

Make spaces between horizontal options the default attribute.
Rename uber-function to lightbar_func.
Add object support.  Create a new Lightbar object with:
var lb=new Lightbar();
Or optionally specify items like so:
var lb=new Lightbar([{text:"Option1",retval:"1"},{text:"Option2",retval:"2"}]);
Add a new option to the end of the items like this:
lb.add(text, retval [, width]);
Clear the items array using:
lb.clear();
Execute the lightbar with:
lb.getval([currentindex]); // Returns the retval for the selected item

Properties are:
  xpos: Horizontal position of lightbar menu (1-based)
  xpos: Vertical position of lightbar menu (1-based)
  items: an array of objects each having the following properties:
         text - The displayed text.  A | prefixes a hotkey
         retval - The value to return if this is selected
       OPTIONAL Properties:
         width - The width of this item.  If not specified, is the width of
                 the text.  Otherwise, the text is truncated or padded with
                 spaces to fit the width.
  direction: 0 for vertical, 1 for horizontal.
             Horizontal menus always have one space of padding added between
             items.
  fg: Foreground colour of a non-current item
  bg: Background colour of a non-current item
  hfg: Foreground colour of a current item
  hbg: Background colour of a current item
  kfg: Hotkey forground colour for non-current item
  khfg: Hotkey foreground colour for current item
  current: Index of currently highlighted item (ToDo: This should be passed by reference (how?)!)
  align: If width is greater than the text length, a zero indicates the text
         should be left-aligned, a 1 indicates it should be right-aligned, and
         a 2 indicates it should be centered.

The Lightbar object will display a list of options and prompt the user for
a selection if lightbar_func() returns NULL.

Still todo... make the current value stay at the last selected one.
