2592506288 Implement parsing of simple :find expressions. (#196) r=nalexander
* Test the mentat_query directory on Travis.

* Export common types from edn.

This allows you to write

  use edn::{PlainSymbol,Keyword};

instead of

  use edn:🔣:{PlainSymbol,Keyword};

* Add an edn::Value::is_keyword predicate.

* Clean up query, preparing for query-parser.

* Make EDN keywords and symbols take Into<String> arguments.

* Implement parsing of simple :find lists.

* Rustfmt query-parser. Split find and query.

* Review comment: values_to_variables now returns a NotAVariableError on failure.

* Review comment: rename gimme to to_parsed_value.

* Review comment: add comments.
