Moving Profile and Project tab buttons into navbar and removing tabs
* Profile button in nav bar now calls profile modal when logged in
* Add repo button in nav bar now calls repo modal when logged in
* Project buttons in nav bar now call edit project modal when logged in
* Removed tabs (still more code to remove from other pages)
Removing project and profile tab code that's no longer needed and minor style changes

* Removing _nav_bar and _edit_projects partials
* _edit_profile partial is now just the edit profile form modal
Small fixes to modal column alignments
