[Marketing] OSGEO -> OSGeo, really

[Markus Neteler]

Hi Marketing team,

I see more and more OSGEO rather than OSGeo being used.
That's diluting the brand IMHO...

examples
- http://wiki.osgeo.org/wiki/PDX_OSGEO_20111026_Meeting
- http://wiki.osgeo.org/wiki/OSGEO_Local_Chapter_recognition
- emails with outreach goal
etc

I'd suggest that OSGeo marketing posts an official reminder how
to write "OSGeo".

thanks
Markus
