Sessions broken in 0.4.0 (includes hotfix)

[Michael D. Ivey]

We've gotten several reports on #merb that each request gets a new  
session ID in 0.4.0.  I quickly tested and verified.  scoundrel  
tracked it down, and I think it's fixed.

If you need to apply this by hand to your 0.4.0 install, it's a 1  
line fix:

This will be in 0.4.1 when it comes out RSN.
