Title: Added a today at midnight fucntion, however

I followed the original libraries pattern for testing it, which could be improved upon.

If you don't mind I can use a date util to test it, with the time fixed:
https://github.com/AlexBaranosky/Utilize/blob/master/src/utilize/testutils.clj

I didn't want to add another dependency to clj-time without asking first.

Another option is to just copy and paste it in, which I'd avoid, but its all up to you :)
