//History

//v0.1    Experimental Cross beam app. Works for NDTMSC. Button is buggy.
//v0.2    Fixed bug: Ships in deep space could not open shipscreen.
//v0.3    Fixed bug: Now correctly targets foreign ships, not just highest ID foreign ship.
//        Added: "Changed Target" warning added. Cargo in old beam now dropped to surface.
//        Updated: crossBeamTarget() now more consistant with other code
//v0.3.1  Updated: lets you overload target cargo bay to destroy cargo
//v0.3.2  Updated: lets you overload target fuel tank to destroy fuel
//v0.4    Optimised transfer() code
//v0.5    Horwasp fixes


//To-do:
//Toggle overload beam on/off??
