Peace Corps Projects pages

WIP. Not ready to merge yet.

Includes:
- [x] view and template for the donate landing page
- [x] models, view, and template for individual projects
- [x] models, view, and template for issues
- [x] sql dump of dummy data I added for testing

note: I did not add the test images I used, because I'm not sure of the copyright on some of them.

Still needs doing:
- [ ] tests.
- [ ] make the templates presentable
- [ ] set media root, which determines where filefields upload to
- [ ] set image urls so they can be included in templates
- [ ] country fund pages
- [ ] general fund page
- [ ] special funds
I like this implementation
