parse mssql options from query string

I needed to set the requestTimeout for a long running query but it seemed to me from the source that the options were being ignored. I'm not a node developer so couldn't figure out your tests but I did run a few manual tests on it. Thanks for an awesome sql client!

Hi, thank you for contribution. I really apologize for delay with merging it. We don't have auto tests so I need to review and test it manually. Currently I'm on vacation. ETA ~2 weeks.
