. Improvements to portlet session handling in Login/Logout situations

- Storing of "inPortal" flag in a Threadlocal
 - No longer invalidate portlet session on logout - clear session by hand instead
   - Makes it easier to integrate with other JSR-168 vendors such as Liferay
. Added the current template NodeRef to the default templating model
   - Accessable as an object in the root of the templating model called "template"
. Added the current script NodeRef to the default scripting model
   - Accessable as a root scope object called "script"
