* Changed BLocaleRoster::GetLanguage() to a signature that makes more sense,

Browse Source 
and looks more like the rest of the API.
* Also, it will now return an appropriate error code if the language couldn't
  be allocated (anything else than B_OK is an improvement :-)).
* Several changes in BLanguage:
  - GetName() now gets a BString reference, also
  - it now returns the name in its own language, ie. for German this would
    always be "deutsch", no matter the current language settings, and finally,
  - it now empties the string it gets before adding the name.
  - added GetTranslatedName() that behaves like the previous version.
  - added const where it made sense (ie. almost everywhere).
  - Code() now returns the code of the language only.
  - ID() now returns the full ID of this language, ie. including country,
    variant, and keywords if any.
  - added Country(), and Variant().
  - renamed IsCountry() to IsCountrySpecific().
  - added IsVariant().
* Cleaned up Language.h, minor cleanup in LocaleRoster.cpp.
* Removed the whole move item logic from LanguageListView; while this was not
  only spaghetti code, it doesn't make much sense in the first place.
* Instead of removing stuff from the left, and even worse, moving all countries
  for a language even if only one had been dragged, we now only mark the items
  that are already in the preferred list, and only those.
* Fixed various mixups of FullList*() vs. *() methods that could lead to things
  like bug #5896.
* Pressing the delete key in the preferred list view will now remove the
  language.
* Moved LocaleWindow specific message constants to LocaleWindow.cpp; Locale.h
  is supposed to contain application wide constants.
* The drop logic is now in LocaleWindow.
* We now make sure that each base language can only be in the list once.
* Lots of cleanup, even though I mostly replaced spaghettie code with different
  looking spaghettie code - still, I think things have slightly improved.
