1.1 Don't use the plugin_get_buffer() so the playlist viewer should work with this plugin running;
1.2 Added new columns for charger inserted, charging, usb powered;
1.3 Some other small improvements
2. charger_inserted() again returns only the AC/DC charger state on H3x0, doesn't include the usb state;
3. Some ifdefs corrected in power.c and power.h;
