Added delay to paste (#1007)

* Added delay to paste

If keys are still held down while it starts typing this can trigger commands or alternative characters to be typed, may need to add a description to warn people if they don't understand how this script works? Not sure if that's standard practice for these commits

* Added alert window and modifier key check

Returns an alert window to tell the person not to hold modifier keys while the script runs, also added a brief pause before it runs to allow them to release the keys
