added skills.xml

also made a small modification to Skill.java, adding another
constructor without the subName being required.
Positive traits added
began adding negative traits

I stopped because I need to think about exactly how I want to bring in
negative traits into the program. either just by parsing in the number
with a '-' in front (I believe that javas in parse will understand that)
or if I want to have a boolean negative value.
traits.xml - negative traits added

This adds in all the traits that are in the basic CBT:RPG book. There
are still extra traits from companion and clans. Possibly a few in other
books as well. But for testing the xml loading it should be fine.
header update
Successful test of reading xml file

The skills xml file read in perfectly. Populating a linked list of
skills with all of the skills listed in the xml file. It took in their
names as well as the boolean value for weather or not they are
difficult. While doing this I realized that I will need to adjust the
way that the xml file for traits is set up so that it will be able to
read into the program correctly.
small changes to source

fixed a typo, and commented out the older test, so that just the skills
list will show when run
added XMLReader.java which takes code from Source.java
big update to skills

skills is now read in properly through the XMLReader class, Game data
now contains the LinkedList of the skills for the program to work from
and will contain the data for the other LinkedLists as they are
finalized. Finally, skills now have the military boolean, as there are
often stages in life paths where characters get free skills to any
“military” skills. Unfortunately what is “military” is left at GM
discretion so I just had to do my best to assume what constitutes
military.
Massive Update

Traits are now implemented and are read in from their xml file. To
allow for the different methods that traits increment their value. 2
boolean values were added to accommodate this. One if the trait
increments by odd numbers (1,3,5,etc) or if it does it by addition
rather than multiplication. Also added the incrementPoints methods in
skills and traits, which should be used in place of the standard setters
Cleaned up old imports

When I pulled out the original XML reading code, I left the imports by
accident.
