Added some tips for implementing user favorites.
Implementing Super/Subskills interface

Interface added to search for subskills.
-Need to implement check in displaySkill to see if subskill argument is
passed in.
--Maybe just make a new script that does this instead of adding to
displaySkill

Fixed the double encoding bug. Introduced new bug where obscure
characters cause errors with the GET requests. Probably an encoding
issue again.
