Fix'd up changes made on Goal Tab

1) Made some technical modifications to the Goal tab's functionality
a) created a separate class (called "Goal.java"). This is where the data
members are accessed for a profile's goals.
2) removed some placeholder strings on jLabels and jPanels
3) updated the Profile's current weight so the Goal Tab would register a
difference in original weight at time of Goal creation and the current
weight of the profile.
4) fix'd the percentage bar
5) modified PrintHelper class a bit
6) created a new Jar file
