support for additional language

Hi,

codemirror itself contains support for a language called Cypher, see https://github.com/codemirror/CodeMirror/tree/master/mode/cypher

Is there an easy way to enable this for the plugin? The current plugin version 1.2.3 does not have Cypher in the language list.

Aside from this: a really awesome plugin. Thanks for providing this.

Cheers,
Stefan
