Add the list of top ten agencies and their statuses

- The Ruby code that retrieves the data works but needs *desperately*
  refactoring, which I'll tackle.
- All of the data isn't here yet - transition managers also want
  their RAG status and the transition target date - but this proves
  that it's possible.
- Resize the existing widgets to make room for this one on the same
  line.
- Reduce the font-size on the list widget a bit so that the agency
  names don't overlap with their statuses.
By CamelCase the status, I meant Titleize. Actually do it now.
Refactor the data retreival for the top ten transitioning orgs table
Fix an off-by-one error

- This removes the spreadsheet column headers from the list widget.
- Fix terminology in a comment.
Add the target transition month and RAG status to the widget
Name the top_ten_agencies hash keys according to the value description

- Not just non-descript "value".
Fix the org_top_ten list alignment with an HTML table and some CSS
Ignore the potentially present "- live" in the target month data

- There's currently a "February - live" target month for UKBA - it
  looks messy in the table.
Remove the abbreviation for "business as usual" for ease of reading

- Discussed with William Reddin.
Remove superfluous `|orgs|` in (0..9).each block
Further refactoring of the spreadsheet data retrieval code
Remove unnecessary animation config in the list widget JS

- The list widget data was set to animate when it loaded, but it
  doesn't seem to be working and this - touchwood - does nothing bad
  to the widget. At least there's no potential for distracting people
  with animation now it's removed.
Split the data retrieval XmlSimple...RestClient... line into two
Change the `data` hash in the data retrieval method to an array

- The `data` hash only had numeric values as keys.
- Adhere to the style guide with Array.new without parentheses.
- Give the data retrieval method and a variable more descriptive
  names.
Make the spreadsheet URL a constant
Simplify spreadsheet method
Refactor Spreadsheet code
