CrashPlan menu bar

The menubar displays backup status to each enabled destination and from each inbound source computer.

The logging level has been increased for debugging purposes in this reiease and ~/Library/Logs/CrashPlan/menubar.log.0 may grow slightly larger than your normal CrashPlan log files. The final version will log at less verbose levels.

Requirements:
- Mac OS X 10.5 or higher
- CrashPlan version 3.0.2
