[MlMt] Support for Gmail labels

[Benny Kjær Nielsen]

Hi MailMate users,

I know a lot of you use Gmail and I wanted to let you know that the 
latest test version of MailMate has support for Gmail labels. I added 
this just because I figured out how I could do it ;-)

Gmail labels are mapped to IMAP keywords and thus implicitly to MailMate 
tags. There is no GUI support yet for setting it up. You'll have to edit 
a file to map individual labels to tags. After that it'll be just like 
using tags, but for Gmail accounts the tags are mapped to Gmail labels. 
Read more about this in the release notes.

Hold down ⌥ when clicking “Check Now” in the Software Update 
preferences pane to get the test release (r3752). Don't expect it to 
work flawlessly and don't forget to send feedback. (It's been added to 
MailMate within the past 24 hours.)

Have a nice weekend.
