HaikuDepot : Improve Language Code Handling

HDS is soon going to be enhanced to deal with more than
just the two-character ISO language codes that it
currently supports. The logic in HD is currently expecting
that HDS will only supply these two character codes. This
change is about making adjustments to be able to cater to
any ICU language IDs from HDS.

The naming in HDS is still going to continue to use the
terminology that it currently does; it will call the
identifier for a language a "natural language code". The
HD source will instead reflect the nomenclature of ICU
and call the same thing a language ID.

HaikuDepot: Lists; Categories + Stabilities

Remove use of custom list class where it is not
really required in the area of Categories. Also
introduces stabilities relayed over from the
Server and used in the HD user interface instead
of being hard-coded.

HaikuDepot: Languages List

Abstacts the list of supported languages into

logging techniques may have caused incorrect
logic flow.

HaikuDepot: Better Logging of Cache File Creation

A user has reported having some problems around
initial use of HaikuDepot and this seems to be
related to setup of the directories etc... at
start time. This change should improve the
logging so that it is easier to identify the
cause. Also some additional locking has been
introduced as there might be a problem where two
threads are creating the same directory at the
same time.

HaikuDepot: Categories from Server

The list of categories for packages is currently
hard-coded into the HaikuDepot desktop
application. This change will change that so that
the list is obtained from the HaikuDepot Server
system and is always up to date with the server's
list of categories.

HaikuDepot: Load Languages from HDS

The HaikuDepot application has, thus far had its
own hard-coded list of languages that the user is
able to choose when (a) creating a new account or
(b) creating a user-rating. This change will mean
that those languages are loaded from the HDS
server dynamically and in this way the user can
choose from the full list. There have also been
improvements to the way in which the languages are
displayed in the menu as well.
