DrJava Legacy SVN Repository

This commit contains two new features:
1) Drag-and-drop for Java files. Files from Windows Explorer,
MacOS Finder, and Nautilus on Linux (other file browsers not
tested) can be dragged and dropped into DrJava. Since
drag-and-drop targets are enabled on a per-component basis
and not globally for a frame or application, there are some
parts of DrJava's GUI that are NOT drop targets. However,
most big GUI parts, like the list and tree navigators, the
interactions pane and the definitions pane, are enabled as
drop targets.
2) Connecting to a running DrJava instance to make it open
files. When DrJava is started and a file (or files) is
specified on the command line (or by dragging and dropping
a file over the DrJava exe on Windows), DrJava will attempt
to open the file in an already existing instance of DrJava.
If no running instance is found, a new instance of DrJava
is started and the file opened. This is accomplished by
letting the first instance of DrJava listen on a socket
(default: 4444) and having subsequent instances send a
message to that socket. If there is no response within
250 ms, it is assumed that no "remote control"-enabled
instance of DrJava is running. To force DrJava to always
start a new instance, the -new command line switch can
be used.

There was a mismatch between the return values of several the "save"
and "close" functions; some used true to indicate success, others to
indicate failure.
