Added 'createRequest' method

Figured out where to put meteor methods - built in callbacks too!

call the function with:
Meteor.call( 'createRequest' , args, function(error, result){});

check server.js to see what args should look like. I thought it would be
better as an object than one long ass set of params. If there's a more
convenient way to pass the parameters from your perspective let me know!

Next up:
-add login check to createRequest - it currently breaks without an
userId
-move other global functions to Meteor.methods
-migrate other global functions to
