[Schevo-devel] quick branch idea -- use external Durus

[Matthew Scott]

Now that Schevo has been setuptools-ized for quite some time, I think  
we should explore the idea of using a specific version of Durus as an  
'install_requires' dependency in Schevo, rather than keeping it in  
schevo.store.

If we did this, we'll need to do some sys.modules hacks to ensure  
that existing Schevo databases that have references to schevo.store.*  
classes will transparently use Durus classes.

For a given release of Schevo, it would be pinned to an exact version  
of Durus to ensure stability, but this would certainly make it easier  
to update Schevo to use the latest Durus now (which it isn't yet) as  
well as in the future.
