Implementing custom MessagesMap class

[Karol Borkowski]

Hi,
I'm trying to implement custom MessagesMap class, so that resource 
bundles will be searched in addional location. Unfortunately, when I 
override method ensureInitialized() i don't have access to CacheKey 
class, because it's private inner class of MessageMap.

Is this an error or should I write my own CacheKey class also?

PS. I've been using click for over 2 years now, great work - can't wait 
to check new release!
