Introduce initial middleware draft
Don't wrap requests in Rack::Response when not needed
Get the original exception in DebugExceptions monkey patch
Prioritize web_console.exception when picking creation scheme

It may happen that application code sets web_console.binding first and
then the app fails. The console pages will spawn a console in an
unexpected binding then.
Add a test to guard for web_console.exception priority
Extract WebConsole::Request for all web-console specific request ops
Extract the controller and view helper into a single module

It can be shared between the two at the moment.
Raise WebConsole::DoubleRenderError for multiple console calls
Include the ActionView helper at the right place

Once ActionView::Helpers is included into ActionView::Base, including
more modules into it, won't make the methods findable by
ActionView::Base instances.
Revamp WebConsole::Request documentation
Merge pull request #69 from gsamokovarov/introduce-middleware
