gidlc working in gephex--main--0.5

Yesterday I merged my changes from
[email protected]/gephex--georg--0.5 into
[email protected]/gephex--main--0.5.

I have almost completed the implementation of the interface compiler gidlc.
It is integrated into gphxcore (where it creates the c++ wrappers for
various interfaces)
and into the numbers plugin (where it creates a lot of glue code and c++
wrappers).

Since then, I did some more changes in
[email protected]/gephex--georg-pluc--0.5
to make pluc work. It is now used in the numbers plugin. What's missing
there is the
functionality to create automake files from a project specification, to
create skeleton code
and to create the code that is exported from the plugin (dock, board,
unboard).
This should be relatively easy.

All files in plugins/src/numbers except kalkulonunit.cpp/hn
numberlink.cpp/h, and
number_export.c/h are auto-generated. At the moment there are very many
generated source
files - I plan to put most of them in one big cpp file instead, to speed
up compilation.

The files ending with "wrapper.*" are C++ wrappers of interfaces, the
files ending with
"glue.*" are C glue code that wraps the C++ classes with c functions.

I would be glad if you could review these changes
(in [email protected]/gephex--georg-pluc--0.5).

Note: at the moment attaching links to units is broken, but that should
be fixed soon.
Importing LinkFactories and UnitFactories works, as well as creating
units and links.

Regards,

Georg
