#2 GeneratorTask: checkJacobeConfig fails if jacobe is not conf

[Daniel Doubleday]

if jacobe is not configured at all the generator task
will still try to run it.

snip: (checkJacobeConfig())

if (jacobeExeConfigured && !_jacobeExeFile.exists()) {
log("The specified jacobeExeFile " +
_jacobeExeFile.getPath() + " does not exist.",
Project.MSG_WARN);
} else {
jacobeExeFound = true;
}

will set jacobeExeFound to true if jacobeExeConfigured
== false
