Add Deskbar clock settings to Time Preferences

* Added a new Clock tab to the Time preflet. Added Clock related
controls there. They all function by communicating with Deskbar.
* Put controls in a BBox controlled by the Show clock checkbox.
This more clearly shows that all the clock settings are dependent
on the show clock setting since it doesn't matter what your clock
settings are if you don't show the clock.
* Make revert work.
* Split clock settings into it's own file and struct.
* Re-add the time zone setting.
* Remove the clock settings from the Deskbar preference window, they
are in Time now.
* Make Locale preferences accepts B_LOCALE_CHANGED message, although
not used.

Instead of destroying the BAboutWindow object on close, Hide() it, then on the destructor of the calling window call Quit() explicitly to destroy it.

Use a quit bool in B_ABOUT_REQUESTED to indicate that the about window has quit instead of using kAboutWindowClosed message. This prevents message signature clashes.

Set the about window object to NULL on close or quit.

Pass the BHandler object that opened the about window to BAboutWindow.
When the window closes, send a kAboutWindowClosed message back to the
handler. This allows the handler to set the variable to NULL.

Implement the new about dialog constructor in all apps that use it.
Remove the old constructor. This now works reliably for all cases I
tested without crashing and does the right thing on close. The setup
and teardown is a bit more complicated than I wanted though.
Unfortunately this seems to be necessary when not using a BAlert.

Fetching the app icon does not work reliably yet. This is because for
replicants the app may not be running. I may have to pass the icon in
instead of grabbing it from the signature.

More catalog-related cleanup.

* rename B_TRANSLATE_CONTEXT to B_TRANSLATION_CONTEXT and
B_TRANSLATE_WITH_CONTEXT to B_TRANSLATE_CONTEXT, squashing a TODO
* adjust all uses of both macros in Haiku's source tree
* use correct header guard for collecting/Catalog.h

The renamed macros require adjustments to all external applications
using catalogs.

Introducing a Locale option to display localized filesystem entries (primarily apps and folders) in Deskbar, Tracker, etc. Making use of this in Deskbar's list of apps. The option currently defaults to off, to avoid exposing everyone to unfinished work.

One more monster commit (sorry ...) concerning the Locale Kit:
* extracted new class BFormattingConventions from BCountry, which
manages the formatting conventions from a given locale and
allows to get/set the four different date/time formats supported
by ICU-locales as well as number and monetary formats
* overhauled the Locale preflet:
+ drop editing features for all formats, since I don't think
they do not make much sense to have in a prefs GUI - being
able to select from the existing locales should be good
enough. Please note that you can still change the formats
programmatically in an application.
+ renamed the 'Countries' tab to 'Formatting'
+ the locale formatting conventions list in the 'Formatting'
tab is now hierarchical for easier access (less scrolling)
+ fixed functionality of 'Revert' and 'Defaults' buttons
+ added support for using the month/day-names of your preferred
language during date formatting
* adjusted BLocale to ask BFormattingConventions for the current
formats when formatting dates and times and to offer 4
different format styles (full, long, medium and short).
* adjust all classes formatting dates/times to pick the
appropriate format style
* BLocaleRoster no longer directly archives/unarchives the
individual formatting conventions but delegates that to
BFormattingConventions

Adjustments to Locale preflet
* renamed Locale.{h,cpp} to LocalePreflet.{h,cpp} as having two headers named
Locale.h confuses jam (as a result, the Locale preflet did not depend on
headers/os/locale/Locale.h)
* style adjustments (mostly order of headers)
