[Radiant] Caches and environment - or: how to add extension configuration?

[Sean Cribbs]

Are you running in development mode?  If so, that filter will be 
reloaded on each request, but your configuration in environment.rb 
won't.  In general, it's better to put configuration in Radiant::Config 
if possible, which stores its values in the database.
