[RUBY] If VIEW (template) is not reloaded by changing RACK_ENV at the time of development with Padrino, enable reload_templates.

I'm using Padrino, a Ruby framework somewhere between Rails and Sinatra, but Reloader didn't work and the controller reloaded but the view didn't reload, so I looked it up.

The cause is that RACK_ENV was changed to development_xx. The solution is to specify the following in app.rb.

enable :reload_templates if RACK_ENV =~ /^development/

Padrino, it's not that big and there's not much information on the web, so it might be the shortest to read that in the source.
