• 6208fc36 is for eliminating weird errors such as "A copy of ApplicationController has been removed from the module tree but is still active!"
• 2a32ba10 is a fix to check for the existence of an input parameter
• 48d79a91 was called wf at the time I patched tr8n
• 018839f4 IE 6 & 7 don't understand the html tag. This commit also includes caching changes/fixes. The idea is that find_or_create methods on models do ony that, find or create. Then "for" methods deal with the caching and call find_or_create.
• 14b1d762 is an optimization that skips TranslationKey and Translation lookups when the current_language is the same as the default_language.

Philippe, great additions, thank you. Are you planning to upgrade to Rails 3.1 ? I am making a lot of changes in the master branch now. Is unloadable still required in 3.1?

for 48d79a9 - i have changed the namespace to will_filter - so the master is now referring to it as WillFilter::Filter.

In Rails 3.1 AssetPipeline fixed a lot of issues i've been having with mounting multiple gems. Now it is much better. I hope that everyone starts using 3.1 instead of 3.0 so we don't need to maintain the earlier versions.
