[Mapbender_dev] Mapbender on ohloh - I updated the project page

[Astrid Emde]

Hello,

Christoph gave me administrative rights to manage the Mapbender project
information on ohloh.

I updated the information.

* added the git repositories
* added links to mapbender3.org and updated links
* updated project summary
* added tags openlayers, symfony2, jqueryui

Please have a look at the changes. You may create a user if you are not
registered at ohloh yet.

It would be nice if another person would volunteer to be Mapbender
manager on ohloh.

Astrid
