Add projects data

[peterloveland]

Adds 8 functions:

1. list projects
2. get a project
3. list the project items
4. list the project views (though not sure how useful this one is)
5. list the project status updates
6. post a new status update
7. list repo labels
8. list repo issue templates

I renamed listIssues to listRepositoryIssues. As I understood it, there is a separate api to fetch project issues from repository issues, so making this distinction felt like a good idea.

A member of the Team first needs to authorize it.
