Shouldn't we pass {showStack: true} for test errors?

On this line:

gulp-jasmine/index.js

Line 75 in b8eccd8

cb(new gutil.PluginError('gulp-jasmine', err));

It would be very helpful to include the stack trace here. Otherwise gulp-util just prints a message saying ReferenceError in gulp-jasmine...window is undefined or similar, which is not enough context.
