Adds inital styling for projects pages on dashboard.

- Updates site _custom.scss to match most recent 18f.gsa.gov _custom.scss.
- Adds comment on/off area in fonts.css as a temporary fix for the issue with our 18f font needing absolute paths to function on gh-pages. Can now switch easily between the appropriate section depending on whether you are live or working on development locally.
- Removes some non-essential info from the overview dashboard page. Otherwise, the initial dashboard has not changed much in this version, pending more data to play with and fine-tune.
- Provides 'slots' for many data points on the project pages. Initial layout is immature, but is likely good enough to start getting feedback on what data points are useful to users. See screenshot below that includes hover state on 'contact' square:
