#10 Generate Driver file with similar classname

[Nathan Revo]

I use mainly Java on TopCoder since its what I'm
familiar with. I'd like to see the FileEdit plugin
modified with the following.
1. Allow the Driver filename to be basd on the problem
classname. i.e.
classname: Titles
driverclassname: TitlesTest

2. Add a new tab that allows a template to be set for
the driver file, separate from the code template.

3. Change the JPanel to a JScrollPane for the
preferences page.

Attached is code for all these changes. Please review
the changes and let me know what you think....
