Support for Launchpad S

[szechy]

It would be neat to build in support for the Launchpad S. I'm not familiar with MIDI, but I believe there aren't any differences between the Launchpad and the Launchpad S, other than the name as it appears in line 54 in 'Launchpad.java':

    public Launchpad(PApplet _app) {
    this(_app, "Launchpad", "Launchpad");
}

to this: public Launchpad(PApplet _app) { this(_app, "Launchpad S", "Launchpad S"); }

I would fork the repository and do this myself, but I'm not sure how to rebuild the .jar files to fix the library (Java noob). Any ideas?
