TfsNotificationRelay v1.19.0

New

• Support for TFS 2017 Update 2.
• I got tired of creating all (five!) different editions manually, so I added a Cake build script to automate it.
• With the packaging automated, I took the opportunity to start signing the assemblies. Thanks to DigiCert!

Fixes

• #56 GitPush with gitRepository filter not working well
• #57 Messed up commit order
• #58 PullRequestComment issue on TFS2017.2 (RC)
