Running Scripted Command in separate namespaces?

I've noticed that all scriptedCommands are executed in the Global
Namespace.   I see two problems with this:

1. Misbehaving scripts can pollute the global namespace if they have
subfunctions or global variable in the scriptedCommand.  This give
rise to the possibility of name collisions.
2. In long running scripts that use lots of scriptedCommands, all of
the compiled form of the scripted commands is kept in memory.   This
can cause a lot of extra memory to be used (possibly running out).

I've actually run into both of these in my use of the Beanshell
engine.   I propose the following patch to beanshell that modifies
scriptedCommands to run in a seperate namespace, which solves both of
these problems.
