Small bug in SingleFileLoader with getting file extension

[adzhikemalov]

Problem in this function
private function decomposeFilename(url : String) : void
{
var base : String;
var i : int = url.lastIndexOf('.');

// Get rid of query string if any and extract suffix
base = (url.indexOf('?')>0)? url.split('?')[0] : url;
_fileExtension = base.substr(i + 1).toLowerCase();
_fileName = base.substr(0, i);
}
im using hashsum with floating point like 0.70
and in that case _fileExtension will be "" because url.lastIndexOf('.') is wrong

i fixed it with that changes
private function decomposeFilename(url : String) : void
{
var base : String;

// Get rid of query string if any and extract suffix
base = (url.indexOf('?')>0)? url.split('?')[0] : url;
var i : int = base.lastIndexOf('.');
_fileExtension = base.substr(i + 1).toLowerCase();
_fileName = base.substr(0, i);
}
