ScriptWrapper should be multiplatform
As of right now, ScriptWrapper spawns a new python process with the path to the thp script as a parameter (and the right env), but this won't work in every platform since "python" may not be in the PATH at all.
So I've written a ScriptBundleWrapper, that uses python code.InteractiveInterpreter to run code in its own env. The code for this is in my branch multiplatform_script.
