[ChangeLog] - Disable OHM's idlesuspend.

[Michael Stone]

This is just a small note to announce that, per our decision in today's
software status meeting, I have inhibited OHM's idlesuspend behavior in
joyride in preparation for the 8.2.0 release. You can remove this
inhibition by enabling the 'automatic power management' option in the
Sugar Control Panel's power management entry. We will re-enable
idlesuspend in joyride when joyride diverges from 8.2.0.
