created SkillComparator.java
added TraitComparator.java
Successful test

The comparator classes successfully sorted the linked list of skills
for A-Z based on their name attribute.
Clean up of Character.java

Cleaned up a few of the methods that I had created for the same of
running a test on sorting the linked lists that belong to the Character
Class. Methods are now all alphabetized in their respective section.
Added print support for sub-skills

The print function now checks to see that the sub skill equals “” (i.e.
nothing). else it will append a “/“ and then the SubName.
