Merge pull request #66 from dnagir/webrat

This is pretty necessary for specs like:

` it { should have_selector form }`

With this patch well see the spec as GET #new should have selector "form".
Currently it is very freaking scary:

` GET #new should When you call a matcher in an example without a String, like this: specify { object.should matcher } or this: it { should matcher } RSpec expects the matcher to have a #description method. You should either add a String to the example this matcher is being used in, or give it a description method. Then you wont have to suffer this lengthy warning again.` https://github.com/brynary/webrat/commit/c8eb590b6853dff6198017ebb5...
