This commit creates a wrapper with the purpose of gracefully execute Arcan applications (appls, in Arcan jargon). In a typical FHS system, Arcan can be invoked by a commandline like `arcan <appl>`, or more generally `arcan <arcan options> <appl> <appl options>`. In order to emulate this behaviour, this wrapper was crafted. It `symlinkJoin`s Arcan and the appls, and sets the relevant environment variables accordingly.
