Add the ability to retrieve a list of queued jobs.

This adds a new method to get jobs that are in a queue. This will allow you to see both scheduled and queued jobs.

• all new methods need a test
• this won't actually return scheduled jobs (see here: https://github.com/taskrabbit/node-resque/blob/master/lib/queue.js#L228-L238)
• I wouldn't hard code values to get the "whole" list, but allow those to be passed in. it would be very possible to attempt to serialize more data than can fit in RAM.

[bkohrs]

• Added a test for the new method
• Add parameters to limit what is returned.

Excellent! Thanks!
