Remove unused code / clean-up

[dellamonica]

Track work on cleaning up our code base.

@JohnMulligan, @yl5682 I think this should be a group effort to identify everything that should be removed from the code base.

Triage

Items here should be checked to ensure that they are really no longer needed/used.

• voyage/management/commands/listsourcefixes.py - no idea what this is supposed to do.

To-be-removed

Items here are targeted for removal.

• AfricanName related
  • Models
  • Solr search index
  • Views
  • Urls
  • Html links?
• voyage/management/commands/import_AfricanNames.py - the whole African Names part of the site will be migrated to PAST so this script is obviously deprecated.
• voyage/management/commands/importsourcesxls.py - I have never used this and at this point I don't think bulk source import has ever been required. Moreover, the code is not safe in the sense that Sources deleted will cascade and cause other data to be deleted.

Removed
