MacOS X dmg/app package - please test

@edlnovo

[finally with the homebrew process i got a running app (after solving a few dependency issues i think), stable as far i know (5-6 hrs of testing on normal animation use)

Could you post how you fixed the Homebrew install in my thread:[url]Mac OSX Homebrew install aborts on running synfigstudio]

I would love to at least get one working install, while waiting for the .dmg issues to get sorted. Thank you!

Cheers, G.
