My Campus : localstorage

Added the ability to set a campus as your campus. Links to the location page then go straight to your campus. Also supports hashlinking to go to a section of the locations page. Uses localstorage.

## Todo
- The **Save as your campus** button needs visibly change status between chosen and not chosen
- All links that point to the /locations page need to have the `data-my-campus` attribute added. *Except for the tertiary link to the /locations page. That should always go the /locations page.*
