[DrJava] Update your build-common.xml

[Charles R. <cr...@ri...>]

   I just committed a change to build-common.xml to improve the commit 
process.  Instead of requiring a new Emacs window to enter the commit 
comments, the Ant script will now prompt you for the comments at the 
command line.  This is a huge win for setting up new build environments, 
since we no longer require graphical Emacs on Windows or Mac OS X.

   To get the new change, run "cvs update build-common.xml" in your 
src/edu/rice/cs/ directory.
