Huge change from Viplex Express 3 to 4

Viplex Express 4 changed the nomenclature of what we upload to the posters. Where Viplex Handy and Viplex Express 3 both called these Solutions, Viplex Express 4 now calls them Playlists.

There was also a total reconfiguration of the GUI, version 3 and version 4 are very different softwares.
