https://18f.slack.com/files/ericronne/F02TL5AM4/peacecorps-donationlanding-11-04-14.png

Created a background image class with a centered one for this use case
and a bordered class with white modifier.

Other changes:
- Added left right paddings to all headings, need to fix up.
- Added no bottom margin class for text. Useful for many headings.

Start on project page

Started on layout for project page. Also started on the difficult

Still have to put some volunteer pictures in my local db to test that
part of the layout.

Simple class to create a rounded clipping mask for content or an

Decided not to use "clip-path" css property because its not widely
supported.

Uploaded this image myself.
