Release v0.30 - Where Have You Been All My Life? (#1816)

* run FormatCode build task to fix whitespace/formatting

* correctly flag some GitHub Enterprise tests

* Add Release Notes

* tweak appveyor to not build branch in the repo, when a PR exists already

* travis to only build master branch and PRs

* output actual "dotnet run" command being executed for cake.frosting builds

* update latest Cake.Frosting

* use normal verbosity at the moment due to apparent conflict with "verbose" and latest SDK on appveyor

* try using double dash so dotnet executable doesnt look at --verbosity argument

* travis OSX couldn't download SDK 2.0.3 anymore, lets try the latest 2.1.300
