Fixed 869 Moved edit project link up next to 'Projects' header in profile pg

http://openhatch.org/bugs/issue869  
I moved the url link from bottom of the projects page to the top of the page in the "Projects" header. The previous url link "Add Contributions" was located at bottom of the projects page, making it harder to access when a user has a long list of projects, and the text "Add Contributions" is not clear. 

Please feel free to code review and add suggestions to make this better. Thanks.
