Increased time spent sleeping when using Sleep verb

Boy, I sure do feel sleepy, time to sleep for 2 seconds !

- Increased sleep time for 2 seconds to 5 minutes (BYOND time)
- We just told you you are about to sleep for a while, and anyways
no-one is forcing you (unless you are having surgery, in which case the
beds in the Rest Room are here for a reason)
