[Foss4g2008loc] Sponsor logos

[Tyler Mitchell (OSGeo)]

For those managing the sponsorship part of the website, I've added  
the ability to specify sponsor logos to the OCS now.  They are set on  
the same page that the sponsors are defined:
http://conference.osgeo.org/index.php/foss4g/2008/manager/ 
schedConfSetup/1
Please use a full URL to the graphic files you want to use.

And I also set it up so they appear on the about page, though  
slightly buried under Organizing Team:
http://conference.osgeo.org/index.php/foss4g/2008/about/organizingTeam

I'm midway through making it so they can appear in the sidebar, which  
is the ultimate goal, but this part needed integrating first.  More  
on this to come.
