HaikuDepot : New Parser Generation Script

Without functionally changing the generated
code, create a new mechanic for generation
in order that improvements can be later made.

HaikuDepot: Url -> Identifier

This change will rename the confusing "url" within
HaikuDepot to be "identifier" in line with
corresponding changes in pkg kit and HDS. Also at
the same time support is introduced for HDS
repos' meta-data to artificially match against
multiple repos; as requested for the future R1B3
release process. Some tidy-ups and extensions have
been made to the JSON schema-to-model and the
schema-to-parser scripts.

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.

HaikuDepot : Generate Server Model + Parser

The server uses JSON schema to generate some data-transfer-object (DTO)
models for communication with other systems. This same schema can be
used to generate the C++ .cpp and .h files for use in HaikuDepot. So
far these have been generated by hand and then manually added to the
Haiku repo. Now the schema files can be copied over and from those, the
sources are generated.
