Merb 1.0.8

Hey guys!

We released Merb 1.0.8 today. The notes:

Fix one remaining place where merb.main.pid was being overwritten by merb -i or merb -r.
Fix an incompatibility between Merb middleware and other rack middleware
Missing webrat no longer fatals. It prints a warning instead (so you don't need webrat for model specs)
Support cookies being set by the user directly in request specs
Bump DM versions to 0.9.9 and DO versions to 0.9.10.1
Improve some convoluted code in Haml
Merb actions now wrap DataMapper repository blocks (to support a per-action IdentityMap)

Enjoy!
