Upgrade gulp-bower to 0.0.7.
Specify bower resolution so it doesn't ask/fail.

`bower install` would ask if resolution is not specified.
`gulp-bower` would fail because it doesn't want to bother the user with that :)
Upgrade angular to 1.3.3.
Add hypermedia api.
Output correct links in hypermedia api.
Add ngResource.
Replace todoItems with Todo $resource.
