Update Elasticsearch mappings for ES 6

Reduce amount of data stored, remove aliases, and update for ES 6
compatibility. This is a precursor to #82.

Reindexing steps:

1. Update ES config:

reindex.remote.whitelist=OLD_HOST:9200

2. Reindex from remote:

curl -XPOST 'NEW_HOST:9200/_reindex' -H "Content-Type: application/json" -d '
{
  "source": {
    "remote": {
      "host": "http://OLD_HOST:9200"
    },
    "index": "item_fulltext_index"
  },
  "dest": {
    "index": "item_fulltext_index",
    "version_type": "external_gt"
  },
  "script": {
    "source": "ctx._version = ctx._source.version",
    "lang": "painless"
  }
}'
