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.

Fix #8452 (app's crashing for non-existent system catalog)

* make the system catalog a BCatalog instead of a BCatalogAddOn*,
such that using a non-existing system catalog won't crash but
simply return the untranslated string instead
* rename MutableLocaleRoster::GetSystemCatalog() to LoadSystemCatalog()
and adjust it to use BCatalog::SetTo() in order to replace the
data used by the given catalog
* adjust all users of gSystemCatalog accordingly

Merge liblocale.so into libbe.so.

* Make the locale kit a part of libbe.
* Drop the LocaleBackend kludge used from within libbe (and from
other places, too) in order to access system catalog strings.
This is now done via gSystemCatalog, which is provided and initialized
by libbe.
* Drop all references to liblocale.so from all Jamfiles.
* Add legacy symlink liblocale.so in order to keep optional packages
that rely on it in a working state.

TODO: the documentation hasn't been updated.

Use resource definition files instead of DoCatalogs rule. Rename B_TRANSLATE_APP_NAME and related macros to the more generic B_TRANSLATE_SYSTEM_NAME, to also fits add-ons, folders, etc, and make 'System name' its standard context. Change CodyCam and PoorMan's app signatures to match the overall x-vnd.Haiku-App pattern. Some clean-up. Make SlideShowSaver build again.

Simplifying the BAboutMenuItem and adding it properly to the locale kit's DoCatalogs list.

Remove ellipsis. The about-window is not a dialog requiring additional information from the user.
