Added `scrollbars=yes` as window options for popup modal, to fix non-
scrollable issue on new adaptive orcid.org website.
Set OmniAuth provider option provider_ignores_state to true. This makes
OAuth links to the app from other sites work without the `state` parameter,
including the import wizard links on orcid.org.
Added handling to de-munge comma-delimited name list in the other_name
field in an ORCID profile. ATTN this be a temporary measure until the
other names info is handled properly on the ORCID side.
Handle OAuth requests which do NOT use the normal popup window. Like
"import wizard" links from the main ORCID site. In those cases, don't
attempt to close the window and instead redirect to '/' to kick off
the default name search.
Various small fixes to prepare for first public launch of the app.
