Added waypoints for npc #3562 Alaindia

These are my 3 files for updating the patrolling of Alaindia around Darnassus.  This is my 1st pull request so I'm not sure I've done everything correctly.  Couldn't work out how to change the comments to each commit so all I bloody ended up with was Create blah blah.....  Let me know how to change these please and any other things I might have arsed up.
