• Remove the requirement for the dimensions plugin, which is included in
  jQuery 1.2.6

• Bugfix - In IE 6, the iframe layer had a great z-index than the actual calendar,
  so would obstruct it from view (#2683)

• Moved the z-index and other CSS declarations from the Javascript into the CSS
  file for easier customisation (#1521)
• Bugfix - The current month should always be stored using the first day so we
  can be sure that day exists when the month is changed (#1717)

Version 1.1.3

• Bugfix - Customisations (translations etc.) now work in IE 6/7 [Heads up:
  Christian Jarhult]

Version 1.1.2

• Bugfix - Manually trigger a change event on the input when we change its
  value. [Heads up: Arne-Kolja Bachstein]
• Bugfix - Don't allow IE6 select lists to show through. This was supposed to
  work but I obviously neglected my testing duties! [Heads up: kgmiller]

Version 1.1.1

• Bugfix - Make the stringToDate function a bit more forgiving. Previously
  it wouldn't accept international characters in the month name (e.g. Mär)
  Now the month name is only required to be a positive number of non-space
  characters. [Heads up: Arne-Kolja Bachstein]

Version 1.1

• Localise the $ function for the whole plugin, for better compatibility
• Add an options argument, a simple way to customise or localise the plugin
• Add a start_of_week option and make the code more general to accomodate this
• Hide the date selector if a click is detected anywhere within the window, not just in the body of the document (only for browsers which support window.onclick)
