macAppBundle plugin breaks the build on Linux and Windows.

[msgilligan]

The workaround is to comment out some lines in beelinj-browser-fx/build.gradle.

Try commenting out:

1. The macAppBundle closure (currently on lines 27-34.)
2. The inclusion of the edu.sc.seis.macAppBundle Gradle plugin (currently line 3.)

I'll look into a way of making sure this plugin doesn't activate on Linux and Windows.

I reported this upstream as crotwell/gradle-macappbundle#33 for the macAppBundle Gradle Plugin.

This means the macAppBundle can still be built on Windows and Linux, but it won't be built with a bundled JRE. Since I don't expect Windows or Linux developers to be building a full Mac release for a while (though this may change if we start using a CI server) I think we can probably close this issue.
