No need for jQuery just to fetch a document
Use png for chrome notification icons

- I could have sworn SVG worked with chrome 39, but it isn't working in
  chrome 40.
Better handling of internal cmdline options

- don't combine --debug and --help parsing with the Fcommand's minimist
  optspec.
- pass the full command line to minimist.  This means the internal options
  can be passed as the first words in the command line, rather than after
  the Fcommand
Nothing currently using jQuery
Include spec-factotum in tests

- but disable all its tests because they're old and not applicable in their
  current form
Normalize internal Fcommand options
Use nested describe()
Fix handling of --debug

- since --debug can be a string or a boolean option, if it's specified
  with a non-= argument, it is considered a string with no value.  This must
  be mapped to true.  This implies that the only way --debug can be given a
  value of "bg" is with = (this is inherent in minimist).
Modify default omnibox suggestion

- include an indication if the fcommand is being invoked with internal
  options
- function rename so that it's clear when we're only retrieving a command
