Release 0.1.7

The inclusion of Enumerable(QueryResult) in RethinkDB::QueryResult failed to satisfy the abstract type checking of Crystal v0.30

Whilst we could expose enumeration, using the #as_h and #as_a methods are more explicit.

Changed

• #as_a returns Array(QueryResult)
• #as_a? returns Array(QueryResult)?
• #as_h returns Hash(String, QueryResult)
• #as_h? returns Hash(String, QueryResult)?
• RethinkDB::QueryResult::Type is now analogous to JSON::Any::Type
• reql spec helpers moved from spec/reql_spec.cr to spec/spec_helper.cr
• added skip methods

Removed

• Enumerable(QueryResult) on RethinkDB::QueryResult
