[Soot-list] use soot in new eclipse plugin

[Jian Xu]

Hi:
I've review the code in the SootLaunch and I find many other information
about ClassLoader ContextClassLoader etc. I find if I call some Soot class
before using reflection to call Soot.Main the Soot Plugin will fail. I guess
Soot Plugin is dependent on Soot Lib Plugin, so if I initialize Scene class
before using reflection, the classloader loade Scene class is the OSGI
baseclassloader not the SootThread contextclassloader. I wonder how it can
work.

I create a new class extends Thread. Then set the Thread contextclassloader
with correct URLs. Then load my main class but it still throw exception and
say "couldn't find class: xxx (is your soot-class-path set properly?)"
