Title: Adding GET /_aliases capability

If `Server#aliases` is call without `body`, then it is interpreted as a `GET /_aliases` request that returns a hash in the format of index name => aliases.

See "Retrieving existing aliases" section of http://www.elasticsearch.org/guide/reference/api/admin-indices-aliases/
