fixed conflict with MapAction.csproj: this branch has renamed it to MapAction_core.csproj and meantime a new line had been added to the file on master.

Need to make some updates to GOCD:

• Cannot build the installer project using MSBuild, so need to call devenv (the visual studio executable) to do it instead (http://techproblemssolved.blogspot.com/2009/05/msbuild-and-vdproj-files.html)

• e.g. C:\Program Files (x86)\Microsoft Visual Studio\2017\Community>DevEnv "C:\Users\zool1301\Documents\GitHub\mapaction-toolbox\arcgis10_mapping_tools\MapAction-toolbox.sln" /build "Release|Any Cpu"

• This in turn fails due to a bug with out of process building of installer projects (https://stackoverflow.com/questions/8648428/an-error-occurred-while-validating-hresult-8000000a). To fix this a registry key needs to be added, and there is a helper exe installed with visual studio to do this (!): C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\CommonExtensions\Microsoft\VSI\DisableOutOfProcBuild\DisableOutOfProcBuild.exe (https://stackoverflow.com/a/45580775)

• The final convolution is that the helper exe cannot simply be called, because it only works if called from its own folder! So you have to CD to its folder, call it, then CD back to where you were. So we use the batch file created by this lovely person to do that: https://stackoverflow.com/a/41788791.

• So GOCD needs to call that first (no harm in repeating each time) before calling the devenv command. Helper script added and make.cmd updated accordingly.
