plus sign in company name is not escaped correctly

[Kirill Zaitsev]

To reproduce:

1) go to http://stackalytics.com/?project_type=stackforge
2) click on company name
3) type in 'Telefonica I+D' and click on it, you'll get 404 page.

The link is http://stackalytics.com/?project_type=stackforge&company=telefonica%20i+d btw

Looks like comma (,) is also broken. These are the links for Apple, Inc. and Huaxin Hospital, First Hospital of Tsinghua University:

http://stackalytics.com/?release=all&metric=commits&company=apple,%20inc.
http://stackalytics.com/?release=all&metric=commits&company=huaxin%20hospital,%20first%20hospital%20of%20tsinghua%20university

Both links generate 404's.
