wlp-managed extension

Hi guys,

I did some work on the wlp-managed container which I would like to share with you:

1. Support for multiple JVM arguments
2. Support for different context roots (multi war projects)
3. Security configuration for deployed applications
4. And last but not least fail-safe undeployment (xml) -> seems to be an issue when running the wlp within windows and the Oracle JVM

Hopfully you find my contribution usefule and will apply the attached patch.

Cheers
