https://github.com/echiu64/bitHopper

Tested for a few hours, everything looks like it works. Tested with startLP enabled.

New options:
 --altsliceroundtimebias Bias slicing slightly by round time duration with respect to round time target (default false)
 --altsliceroundtimetarget Round time target based on GHash/s (default 1000 Ghash/s)
 --altsliceroundtimemagic' Round time magic number, increase to bias towards round time over shares (default is 10)
