It should be possible to pull in bibliography entries from citesphere

Description
Instead of entering bibliography entries by hand, the user would select entries from Citesphere and those would then be imported. Since Citesphere doesn't have a search endpoint yet, the user would when adding a bibliography block, browse their groups in citesphere and select entries to import. So:

1. user adds bibliography block on a slide
2. instead of adding a reference by hand, they log in to Citesphere (oauth authorization flow)
3. they see all groups they are part of
4. they select a group and then one or multiple references from that group
5. The selected references will be imported into VSpace
   For now, this would be a one time import. We'll worry about updating references from Citesphere later.
   The code that pull data from Citesphere should be its own plugin (have Julia create the basic plugin).
