Add per-mover state machine status to output of FB_XTS

[netbymatt]

In FB_XTS.TcPOU
Declaration is similar to:

VAR_OUTPUT
	MoverPositions	: ARRAY [1..NUM_MOVERS] OF REAL;
	MoverErrors		: ARRAY [1..NUM_MOVERS] OF BOOL;
	MoverErrorIDs	: ARRAY [1..NUM_MOVERS] OF UDINT;
	// ...
END_VAR

Code is similar to

// update global data
FOR i := 1 TO NUM_MOVERS DO
	MoverPositions[i] := LREAL_TO_REAL(Mover[i].TrackInfo.TrackPosition);
	MoverErrors[i] := Mover[i].Error;
	MoverErrorIDs[i] := Mover[i].ErrorID;
