CouchDB v3 related changes

• made sure sofa works with v3; all examples/tests updated to use username/password (#73)
• new function db_bulk_get() for the /{db}/_bulk_get route (#73)
• fixed design_search_many(): in couch v2.2 and greater there's a new route /{db}/_design/{ddoc}/_view/{view}/queries, which is used in this fxn now instead of using the /{db}/_design/{ddoc}/_view/{view} route (#75)
• Cushion class gains new method $version() to get the CouchDB version you're using as a numeric (to enable progammatic couch version checking)
• db_query() changes: some new parameters added: r, bookmark, update, stable, stale, and execution_stats (#74)

DEFUNCT

• attach_get() is now defunct, use doc_attach_get() (#76)

MINOR IMPROVEMENTS

• added more tests (#61)
• design_search() now allows more possible values for start and end keys: startkey_docid, start_key_doc_id, startkey, start_key, endkey_docid, end_key_doc_id, endkey, end_key (#62)
• add title to vignettes (#71)
• for docs_create() internally support using user's setting for the R option digits to pass on to jsonlite::toJSON to control number of digits after decimal place (#66)

BUG FIXES

• fixed authorization problems in $ping() method in Cushion; now separate ping() function calls $ping() method in Cushion (#72)

NEW FEATURES

• Gains new functions db_index, db_index_create, and db_index_delete
  for getting an index, creating one, and deleting one
• Gains function design_search_many to do many queries at once
  in a POST request (#56)
• design_search reworked to allow user to do a GET request or
  POST request depending on if they use params parameter or
  body parameter - many parameters removed in the function
  definition, and are now to be passed to params or body (#56)
• db_alldocs gains new parameter disk to optionally
  write data to disk instead of into the R session - should help
  when data is very large (if disk is used fxn returns a file path) (#64)
