Updated the Top Navigation bar

[Ludachris]

For those that don't like change, I apologize. But I felt there was a better way to group some of the navigation links together so that we might be able to fit a new link up there in the near future. The main changes include the combining of a few of the old links. Here's a quick run down on the naming of the new links and the sections they replace:

Galleries - new menu item
Included in the new menu:
- Photos
- Videos

Marketplace - new menu item
Included in the new menu:
- Parts Catalog
- Classifieds
- Supporting Vendor page
- Supporting Vendor Specials forum link
- DSM Shirts
- DSMtuners Decals
- eBay auction links

Everything should be pretty easy to find. If you come across any errors in the functionality, please post about it in the Site Help forum.

Thanks!
