The installation of 'QZ Tray' failed on OS X

Hi, I couldn't install 'QZ Tray'.

The version of client: 1.1.9-1
The version of OS X: 10.10.3

Please see screens.

I apologise, the problem was I had no Java installed https://java.com/en/download/
However, you could add more informative error message to the installer

PS. 'Getting Started' in https://github.com/qzind/qz-print/blob/1.9/README.md currently leads to 404 - https://github.com/qzind/qz-print/blob/1.9/Getting-Started

Thanks for the bug report. This is related to #37 (fixed) which was prompting to install the wrong Java version.

I'm still trying to figure out how to display a message via the apple preinstall script. If you or anyone else can find a place to add it, we'd be much obliged.
