[GSoC .NET Bindings for UNO, Week 4] unit tests and disable switches

[Ritobroto Mukherjee]

Hello everyone,

Here's a brief update on this week's progress:
- Working on a patch to disable the generation of old CLI bindings with
an autogen switch, as a first step toward deprecation, here:
https://gerrit.libreoffice.org/c/core/+/168751
- Another patch to integrate unit tests for dotnet with gbuild, with
the NUnit testing framework, here:
https://gerrit.libreoffice.org/c/core/+/168956
- Started work on the actual bridge itself. Progress is a bit slow,
with there being a lot of classes to implement and lots of older code
to study, so no patch just yet.

Best regards,
Ritobroto
