[R] namespaces

Yes, I could prefix everything with taskN$, but that's boring!  Can I  
now attach and detach tasks to have one prefix-less, since they look  
like dataframes?  What does proto buy us?

To respond to Uwe here as well, I want dynamic task switching and  
*also* an ability to load and save task from their workspaces into  
their namespaces in the same R session.
