Feature/netcore preparation (#2072)

* Use platform detection that works on mono 4.6+

* Move to use package reference for restoring nuget packages.

* DateTimeRoutines does not have Nuget packages that support .NET Standard (and therefore .NET Core). We will have to include them for now until we can get rid of this dependency.

* Start spliting some interfaces into their own files - this will help by allowing us to split them out in the future into a seperate project so the actual implementations can stay within their respective architectures when required

* Move out common libraries

* Few more tidy up tasks to get things working with .NET Standard

* Restructure the solution layout

* Encoding work to reduce rework later on platforms without Windows codepages (or require compliance with RFC1345)

* Move folder structure around to have more natural layout of the solutions

* DI server configuration to get rid of "temporary" hack and dependency circle for serverservice

* Make all encoding consistent to match the expected encoding casing for earlier versions of mono.
