[Incubator] OSGeo4W project page on the new website

[Helmut Kudrnovsky]

>- For "License" does the main distribution have an open source license (right now it shows "Various" - 
 
of cause it's open source ;-)

reason why "Various" is selected, see https://trac.osgeo.org/osgeo4w/wiki/AboutLicenses

"While each program or package available from OSGeo4W has it's own license, they are all ​open source. For example GDAL/OGR is X/MIT, GRASS is GPL, and uDig is LGPL, to highlight just 3 prominent applications." 

OSGeo4W itself only has two applications, pkg-setup and pkg-apt. All others are simply convenient re-packaging of projects from elsewhere.

> - do you have a screen snap or similar to add to the page?
>- The logo tile needs to be on a white background (or the greens blend together and you cannot see the shape).

we'll have a look in the next days.

Kind regards
Helmut
