[ENH] Faster StarSqueak patch variables

Folks,

a very small but effective enhancement for StarSqueak worlds. To quote from 
the preamble:

Allow custom StarSqueak worlds to go faster by varying the kind of 
Dictionary that the patch variables are kept in.  The default is still 
Dictionary, subclasses may substitute IdentityDictionary, and then have to 
use e.g. Symbols as patch variable names.

This does not automatically affect the supplied StarSqueak worlds, but it 
does help the upcoming StarSqueakLife, as profiling has shown.

Cheers,
Helge
