[MlMt] Latest MailMate test release

[Benny Kjær Nielsen]

Hi MailMate users,

just in case anyone was wondering, the current test release (for the 1.x 
releases) is identical to what has also been released as a kind of 
private 2.0BETA. In other words, I am moving all the new features of the 
2.0 beta down to 1.9.5. I'm doing this because I'm still not ready to 
make a public 2.0 release, but I also want 1.9.x users to get access to 
the new features. In particular, the HTML related improvements. Also, 
the 1.9.4 release does not work well on macOS 10.12 (Sierra).

Note that there is no reason to downgrade 2.0 to 1.9.5 since I'll also 
keep the 2.0BETA up to date and I might, again, add new features to this 
branch first.
