Summary: Change Current Dir of Interactions Pane

Initial Comment:
Story:
User wishes to run a program in the Interactions Pane which 
will try to load a file from the program's "current directory".  
He right-clicks on the Interactions Pane and chooses "Change 
Current Directory...". A confirmation dialog is displayed, 
informing the user that changing the current working 
directory requires resetting the Interactions Pane.  The user 
confirms and is presented with a file dialog to select the new 
directory.  The Interactions Pane resets and the user 
successfully runs the program.

Notes:
The working directory of a JVM cannot be changed once it is 
running.  However, it can be changed on startup.  It would be 
nonsensical to set the directory to the path of the current 
file, which changes much too frequently.  However, the 
current behavior (the directory from which DrJava was 
started) is far too limiting.  This technique should meet the 
needs of most users (given the limitations of the JVM).

I'm still not sure what the best way to change the directory 
on startup is, but I'm certain it could be done.  ExecJVM 
might be able to do it, or we could test whether 
System.setProperty("user.dir", ...) works if it is called before 
any file interactions.  (I seem to recall that it does.)
