Run tests on multiple frameworks (#808)

* Run tests on multiple frameworks

@bording helpfully suggested this in this comment:

#804 (comment)

* Add ref assemblies

* Bump framework version to 3.1

* Add mono to Travis to test net461

* Only test dotnet core 3 on Travis CI

* Do not test net461 via shell script, assuming that mono is not available
