Add RawData request in preparation for manual loading of
Bitmaps and being able to flip them, scale them, etc...

Basically this just makes it possible to download a RawData
directly which you can then pass you'll be able to pass to
pack->CreateBitmapFromRawData.

Some design comments:

I used SetFromFile instead of making a different constructor
since it seemed wrong to do file IO in a constructor. Given
that SetFromFile is private I don't think this is a problem
since you can't call it directly.

Also, I thought about loading the file first and then calling
 the original constructor but it seemed like a waste to load 
the file into memory, then copy it to a new buffer when I could 
just load it directly. 

Finally I made it take a String instead of a FilePath because
it meant other places had to do less work.

Line 174: request_->set_error("Could not download texture: " + request_->uri());
should be:  "Could not download raw data"
