Added  ~2/3 of the moving parts needed for work claiming (issue #6).
Changed wording, use "ORCID record" instead of "ORCID profile". Fixes #7.
Further work on #6, UI and client-side logic finished. Now revamp
server-side code to handle both external id and work id claims.
Nearly all tweaks finished to make claim handler deal with both external IDs
and work IDs, depending on how it's called from the client-side Javascript.
Fixed missing scope and wrong API endpoint. Needed to ask for write-permission for
both external id and works, and different POST URL for each type of POST. bah
Final set of changes to get 1st iteration of work-claiming. Fixes #6
Merge pull request #8 from gthorisson/claimWorksInISNI
