soot-eclipse plugin build changes

[Jennifer LHOTAK <jlhotak@sable.mcgill.ca>]

Hi all,

I added some code to the Soot-Eclipse plugin that requires two Eclipse
plugins:
org.eclipse.draw2d_2.1.2 and org.eclipse.gef_2.1.2.

If you are building the Soot-Eclipse plugin or the
quickstart jar for the development version of Soot, or if you are running
the Soot-Eclipse plugin for the development version of Soot you need to
put these two plugins in your eclipse/plugins directory.

You can find these plugins at
www.eclipse.org/gef
from the downloads page in the runtime section.
Just unzip the downloaded file in your eclipse directory.

Let me know if you have any problems with this.

Jennifer
