2007-xx-xx:
* version 0.6
* THIS VERSION ONLY WORKS WITH FIREFOX 3.0
* IMPORTANT: changed semantics of :echo and :echoerr: Strings must be quoted with " or ' now,
but you can do things like :echo 3+2 or :echo window.document now
* statusline is now white on black with bold font by default (like in (g)vim)
(change with userChrome.css if you don't like it until we have :colorscheme)
* :let mapleader="," and <Leader> in :map support
