wildcards (for txt_for_dir etc.)

//Reads filenames that match the given wildcard/s into separate strings of a text object. 
//This instruction can be used to scan a folder for files matching MULTIPLE wildcards. 
//-----------------------------------------------------------------------------------------
//Parameters:
//targ			Pointer to the target TEXT* pointer for the TEXT object to be filled.
//					If the target TEXT* pointer is NULL, a new TEXT object is created there.
//					If the target TEXT* pointer contains a TEXT object, then the filenames
//					found by this function are ADDED to the END of this existing text object.
//
//pathname		Absolute or Relative Pathname of folder to be searched
//
//wildcards		File names (C-style wildcards) to be matched, '|' separates wildcards.
//					eg: "*.MDL|*.HMP|-*_open.*" This will include all MDL and HMP files,
//					and from that list it will then exclude all "*_open.*" files.
//-----------------------------------------------------------------------------------------
//Returns:
//Number of strings ADDED to 'targ' TEXT object.
