[FLOW3-general] Passing PUT requests to controllers

[Zachary Davis, Cast Iron Coding LLC]

I'm trying to implement a RESTful API for my application. The 
RESTController class is helpful in this regard, and so far it's going 
well. I'm currently working on the update part of the API, and it looks 
to me like PUT requests aren't fully implemented. When I pass values via 
PUT, they don't work. The same values, passed via POST, do work. Looking 
at the RequestBuilder.php file, I see that the PUT portion of the 
setArgumentsFromRawRequestData method is commented out. Is this part 
incomplete, or am I missing something? If it's helpful, I'd be happy to 
file an issue for this or try to find a way to make it work in that 
method if that's the best place for it.

best,
Zach
