feat(avatars): profile images

Getting there! Feel free to start looking @shane-tomlinson @pdehaan.

Still needs:
- [ ] profile-server client
- [ ] progress indicator screen
- [ ] unit tests for camera view
- [ ] unit tests for cropper widget
- [x] circular overlay on cropper
- [ ] functional tests
Just say the word and I'll switch from JSHint to ESLint and we can enforce JSDoc on all the things: http://eslint.org/docs/rules/valid-jsdoc.html
