PowerStatus: Implemented sound cues for low battery and charging

* Added two beep events ("Low battery" and "Battery charged") to Sounds
* "Battery charged" is activated when the battery is fully charged to 100 percent
* "Low battery" is activated when the battery is less than 15 percent
or has less than 30 minutes of usage time left, whichever comes first

PowerStatus: eliminate redundant power notification

patched duplicate low power notifications by adding a flag to
remove redundant notification calls by adding a parameter in
the update function.

Fixes #12277

Fix broken convention

[PowerStatus] The menu item quit doesn't close the Tracker

* Fixes #13790

PowerStatus: convert to BTabView.

* Move text inside battery if possible.
* Fix location of the spark.
* Fixes #5422 and #7330.

PowerStatus: fixed how the info is retrieved.

* The state was usually 0 once there was more than one battery
slot.
* We now ignore missing batteries completely, instead of taking
eventually bogus data into account.
* Fixed how to determine fOnline, and fHasBattery, and when to ignore
probes.
* Made it more strict when to show the notification, ie. it's now only
shown when actually discharging.
* This fixes all spurious notifications for me.

PowerStatus: minor cleanup.

* Moved low battery notification code into its own method.
* Slightly changed low battery notification text.

PowerStatus: removed unused uninitialized variable.

* Might help with #11329; I can't test this right now.

Fix BAboutWindow lifecycle

BAboutWindow returned false in QuitRequested in order to hide instead of closing.
Not only this keeps a BLooper running for a rarely used window, but it also
prevents quitting an application in the window was not destroyed first.

* Remove aforementioned QuitRequested method,
* Add a static GetWindow method that returns the existing about window, if there
is one, or creates one if there is not. A boolean can be set to tell the caller
what happened,
* Adjust all callers to use that new method, instead of managing the window themselves.

Init fAboutWindow NULL first

* The deskbar replicant now memorizes its settings.

* Improved the disabled look (in case there is no battery -- apparently, the
ACPI interface needs some more work, as it currently uses
BATTERY_CRITICAL_STATE to report that there is no battery...).
* Cleanup of many more of Clemens' coding style violations...

* Worked over the battery look a bit, looks much better now IMO.
* Made the replicant transparent (for background images).
* Fixed many of Clemen's coding style violations.

The monitor watcher list was not locked when broadcast a message.
Probably it caused #4151

Add a ACPI battery driver interface to the PowerStatus app. If there is anyone with a working APM please test if its still working!
TODO:
- Get along with the Layout engine, the extended info window looks "no very nice".
- Reading the battery status takes too long so put it into a thread or cache it.

Wrote a small application to show the power status in a window, replicant, or the
Deskbar tray. Currently only works under BeOS, and has rather ugly graphics; Haiku
doesn't have an APM kernel interface yet, and I was too lazy to make any nice
icons/drawings :)
