Working read dictionary and add word functions.

Finally got dictionary read working, as well as loadLinkedList function.
Still need to verify loadLinkedList works as intended, but it doesn't
give any segmentation faults or other error, so we'll assume it works
for the moment. Should rename function since it's not load, per se, as
it is add.

Big cause of problems apparently was char* in my llNode definition for
word. Once I removed the * things started to work properly and as
intended.
