Support for system batteries in ReactOS is really minimal to the point of non-existing. We are detecting the presence of any upcoming battery but since there's lacking in critical code that deals with communication
between PO and the battery class driver as the battery systray icon uses GetSystemPowerStatus to gather battery info which in turn inquires the power manager via NtPowerInformation(SystemBatteryState), we have
to report to the user that the remaining capacity is unknown rather than returning a pseudo capacity value.
Technically this so called "pesudo" value is just a construct denoted as BATTERY_PERCENTAGE_UNKNOWN. Not reporting the actual remaining capacity makes sense, as there could be a scenario where the battery may not
properly report its real datum, therefore it's best to be honest to the user what's really going on.

- Use GetSystemPowerStatus() instead of querying each battery.
- Add an ugly AC power icon. Should be fixed or replaced.
- Display AC power, battery charging, battery depleting and error cases. The AC power case was missing.
- Update some strings because we are no longer using float for the charge percentage.
@Turkish translators: Please check and update the translation of IDS_PWR_CHARGING!
- Volume, Power and Hotplug icon: Use timers to distinguish between single and double clicks.
- Volume icon: Show the tray volume dialog on a single click.
