Add lots of (failing) test cases for problems reported in #14.
Fix 'render :widget' support to properly support all tested use cases.
Rails 3.0.x and 3.1.x have a bug where passing ":layout => false" with "render :widget" simply doesn't get passed through, so let's just disable those tests.
Spec the Content-Type header when using 'render :widget'.
Clean up render :inline support a lot.
Monkey patch ActionController.add_renderer so that if anybody (Erector in particular) tries to steal our "render :widget" support, we steal it right back.
Merge branch 'ageweke/render_widget'
Kill the old SimpleTemplate class, as it's no longer used. SimpleCompiledTemplate is equivalent and much faster.
[17.0ms/24.7ms] Document recent changes. And, still fast!
