official Mac OSX / macOS installers

Thanks to several contributors on github, many people (including yours truly) have been running glogg on Mac for a few months already.

Now that the main blocking issues have been fixed, please enjoy regular official glogg builds from v1.1.2 for Mac OSX (now macOS)!

Enjoy glogg on Mac and please report any problem you might find.

Update 8/11/2016: The initial macOS build for 1.1.2 had a problem and was linked to a local library not available on most systems, and therefore failed to run. This is now fixed and a new installer (glogg_1.1.2-1_installer.dmg) can be downloaded.
