Digest::SHA1 is needed but not required

[jlecour]

Hi,

I can see tha Rack::Bug is using Digest::SHA1 but it's never explicitly required. On some of my apps, it's not required by any other plugin/gem so it's not loaded and I get this :

Status: 500 Internal Server Error
uninitialized constant Digest::SHA1

I've just added the require in the main lib and it's working :
