Feature request: Cache action results.

[eyes2near]

I suggest to give a @Cache annotation to action methods, which will
tell play! to cache all the data it needs to render. When a subsequent
request comes, play can response with the cached data rather than an
invocation to the action.
It could be some code like this:

@Cache(expiration="1h") //expires 1 hour later
public static void cachedAction(){
     //do something
     Object aparam = ...
     render(aparam); // also could be renderXml/renderText/renderJson

It's committed.

I used "@Cache" but the problem is that it conflicts with play.cache.Cache (at least one has to be used with its namespace). Maybe a different name would be better, but I can't think of anything right now.
