Gigabeat S: Implement charging and power control to charge from AC or USB. Hold MENU while plugging USB cable to charge from USB without connecting. Under Windows, plugging USB for charging only but not connecting still needs to be properly handled (driver popup issue) but it will charge when connected normally-- no issue under Linux. Some accomodating changes made to powermgmt.c will soon be made nicer.
