Add carriage returns and indenting for stuff inside WHERE

[freeeve]

Some big queries look bad all on one line, for example:

http://console.neo4j.org/?id=4uugs6

(this one also has the already-fixed issue of extra carriage returns)

Mmh,
yes, intending that would be cool, you think it can be done in a non-hackish way?

CodeMirror seems to have good ways to do it. Just need to figure them out for cypher. I'll probably get to look at it eventually.
