Build: ensure we can build all of our IOCs on one compiler

[Tom-Willemsen]

At the moment the galil driver cannot be built on anything other than VS 2010, but the TWINCAT ioc doesn't build on 2010.

This is a problem, for example on CRISP where we seem to have released a 2010 build and then patched on the twincat ioc and all of it's 2017 DLLs. This setup doesn't seem to be documented anywhere and will break next time we do a release.

As a developer I would like Jenkins to be able to build a single consistent release without the need for individual IOCs to be patched later.

Possible solutions:

• Do the "new galil driver" ticket so that we can deploy a VS2017 build
• At the end of a normal release build, copy the twincat IOC and it's DLLs into the release from a share (essentially what appears to have been done on CRISP, but automated)
• ...?

It feels we are close enough with the new galil driver ticket to finish that
