Add ORCID to registration form

[cthoyt]

This PR demonstrates the following:

1. Adding ORCID to the registration form (character (not varying) length 19 in the database)
2. Rewriting the HTML/CSS for the registration form to use bootstrap (even further, this could use a modal)
3. Adds text during registration about how curations will be licensed and distributed using ORCID, but not email.

How we tested this

We ran cogex locally while on VPN into the hms network and were able to register a new user then login. We might want to do a more detailed test with an actual deployment, but it seems like we're on track.

Should the orcid field be mandatory?

[cthoyt]

Yes

[bgyori]

Why does it have to be mandatory though? Those who want to supply it can but if they don't want to that should be fine too.

If we ask people to provide this information on registration, it increases the value of the curations in that we can connect them to a structured identifier for the creator. I would like to be able to upload statistics of curations in INDRA to APICURON, and therefore ORCID would be necessary to do that.

I don't think it's such a big effort to make an ORCID and copy paste it, so I don't think anyone would complain here. In an ideal world, we'd use single sign on based on ORCID itself (maybe a good project for Tenzin).

That all being said, there's no technical reason that requires this, so if you don't think this is a good enough reason, we can make it optional on the registration.

@bgyori other update - klas and I just tested this, and it works for registration and showing ORCID for people who are logged in!
