List sponsors past and present

[whykay]

List sponsors of Python Ireland meetups/events and PyCon Ireland. Good to recognise our support.

I suggest a page with 2 columns.
on the left meetup sponsors, in alphabetical order, with maybe stars or something if the sponsopred more than once.
on the right, pycon sponsors, grouped by years, and order by level of sponsorship, alphabetical in case of equality.
logo should be displayed.
