Remove Profile111

[richardszalay]

According to ".NET Standard Library - PCL Compatibility", netstandard1.1 is compatible with Profile111.

That being the case, it should be fine to remove Profile111 from the build. The only thing I can see being an issue is it would be dropping support for NuGet 2.x (since it doesn't support the netstandard TFMs)

@onovotny reminded me that NuGet 2.12 supports netstandard monikers so 111 can probably be safety dropped.

I'll be removing this as part of the multi-targeting alignment #61 / 5.0
