Title: Support for $exists

Hello there! I'm using MongoAlchemy (more specifically, Flask-MongoAlchemy) for a project at work, and I noticed that MA doesn't have support for MongoDB's $exists queries.

Since this is rather essential to what I'm doing, I decided to add in support and tests for it.

Please review and let me know if you think anything is missing.

Patrick.
