Feature/iss 304 other names UI

[sibyl229]

UI changes related to other names of Genes #304

• add other names when creating a gene
• add other names to existing gene
• delete other names of existing gene
• autocomplete suggestion to include other-names if available
• recent activities and gene history to handle multi-value other-names
• other-names for split gene product

The PR assumes request body to have the format of:

{
  data: {
    other-names: [ name1 , name2 ... ]
  },
  prov: {
    ...
  }
}

I reverted a change you made to the proxy, to ensure lvh.me will be used during local development (local UI can be used during local API code development).
