Change polling to use nanosleep and calculate sleep times in ms.

Browse Source 
Also fixed the calculation of time to sleep when user is active to not subtract the polling interval and changed idle time comparison to be >= instead of >.
These changes get rid of an extra activity checks before resuming the process and also allow more precise sleep timing.
