Ship TeamSpeak's icon packs with both clients

Default, Default Colored 2014 and Default Mono 2014 now come inside the
desktop JAR and the APK, so the default pack is there without a TeamSpeak 3
install; before, a desktop without one had no icons at all. As with the
sound packs, the builds take them from the TeamSpeak 3 client next to the
repository (ts3.client.dir to point elsewhere) and ship none without it.

Core reads them from the classpath in memory; a pack of the same name found
on disk, in an install or imported, still comes first.
