[steamshovel] [buildbots] Generate nightly/weekly .dmgs for steamshovel

[Hans Dembinski]

It turns out that more than a few people really want to use the Steamshovel app on their Macs (four already just in Delaware). The app is heavy (300 MB), but comes with all non-standard libs included so that it runs on a virgin system without further set-up.

I fixed and generalized the app generator script. It works on Yosemite now, and should also work on Maverick (needs to be tested). Since we have buildbots with these systems running, I think it would be great to use them to generate steamshovel apps on a nightly/weekly basis, and offer those for download. The script takes 10 to 20 seconds, so it is also acceptable to run it on every commit (if that's easier to implement).

The command "make mac-steamshovel-dmg" generates the steamshovel app and compresses it into a .dmg file, ready for installation by users.

outreach in Madison wants a new dmg to get certain newer features.

it would be good to be able to point people to the "latest" dmg whenever they ask.

If they have El Capitan, they can use the DMG that I generate. ​http://icecube.wisc.edu/~hdembinski/
