Changes from 1.0-beta4 to 1.0-beta4.1

• Scores that are whole number no longer show decimal point and trailing zeros.

Known Problems

• Right clicking on things in the tree doesn't show a popup menu in Windows. This seems to be a Java issue.
• Printing probably doesn't work in non-Linux operating sytems. It hasn't been tested.
• The grading scale configuration is rather difficult to use.
• Color preferences/highlighting students with C or lower/hightlighting missing assignments do not update until you move around in the tree.
