Add Appveyor integration

[viciious]

I have troubles compiling the master branch in appveyor due to the following error:

The compiler error looks legit to me. I think that forward declaring a type and then using it as a field or as an array primitive is undefined behaviour.

[mikke89]

Forward declaring it is fine as long as the underlying type is not used. We could solve this by declaring all the destruct/copy/move/destruct members of the parent class, but we might as well just include the header to solve it.

Does this mean you are giving the C++17 version a go? :)

[viciious]

no, why? :P

I'm getting the following issues now:

You're right, thank you! Still learning :)
