Add AppVeyor support about devilution HOT 1 CLOSED

I was able to get this working with the following changes to AppVeyor's default project configuration. This doesn't disable DEP, but it still produces a successful build so should be good enough for CI.

Environment > Build worker image
Visual Studio 2017

Build > Configuration
Release

Build > Visual Studio solution or project file
Diablo.sln

Build > Before build script
CMD
"%VS140COMNTOOLS%\..\IDE\devenv.exe" /Upgrade Diablo.dsw & exit 0

EDIT: You don't need to change the default build worker image, and doing so is, in fact, inconsistent with the call to "%VS140COMNTOOLS%\..\IDE\devenv.exe". There is no %VS150COMNTOOLS% in AppVeyor's environment so it's probably better to stick with VS2015 for devilution. If a derivative project is using VS2017, I would recommend doing a one-time upgrade and then commit the sln and vcxproj files in the repository for that project.
