DrJava Legacy SVN Repository

Changed the Vector*OptionComponents to use a JTable instead of
a JList, allowing for multi-column values like AbsRelFile, which
is file with a boolean that designates whether the file should
be kept absolute.
Now the project extra classpath entries can be entered as relative
or absolute files.

Working on making extra classpath in project properties relative
to project file.
Extra classpath in existing project files that are opened are treated
as absolute, for backward compatibility. New classpaths added from
now on are relative.
Still need to create a way to select whether a path element is
relative or absolute in the GUI.

Fixes bug 2728910: Put (pseudo-)modal window on top when switching back

DynamicJava: Cleaned up type inference implementation; added inference support for union types and disjunctive constraints.

PLT Utilities: Added a static Option.unwrap method which supports a default value with a different type than that of the Option.

Asking DrJava to quit had to occur in the event thread to
avoid briefly displaying errors when shutting down with
files open. If the user cancels quitting DrJava, the shutdown
hook that restarts DrJava had to be removed.
Added indeterminate progress bar while waiting for
sourceforge.net to respond.
