Convert CLI to dotnet tool (#36)

* Convert CLI to dotnet tool

This converts the CLI into a dotnet tool (https://docs.microsoft.com/en-us/dotnet/core/tools/dotnet-tool-install) so that it can be installed via `dotnet tool install` rather than downloading binaries off of github.

BREAKING CHANGE: The assembly name of the compiled output was changed from `sq` to `Squidex.CLI` to comply with nuget standards.

* Allow sq assembly name for all but nuget tool build

For the dotnet tool build packing it means we also have to specify

    dotnet pack -p:PackDotnetTool=1 ...

* Publish cli dotnet tool on build
