Small fix to the bandwidth throttler.

incorrectly charging the entire buffer size against the throttler
rather than just the number of bytes actually read.

For example, if you did a read with a 32KB buffer which only received
300 bytes across the wire, the bandwidth Throttler would charge
you for a full 32KB of bandwidth rather than the 300 bytes that
were really used.  This was grossly overstating the bandwidth
consumption to the throttler.

The functionality is common enough that it may be advantageous for
a third party looking at the request headers to use this method to
calculate the request's expiry date.

Thread safety fix for +threadForRequest

closes gh-205

* If key is empty, don't add anything (value can be empty)
* All file/data methods now do through the long form addData:withFileName:andContentType:forKey: method, to cut down on a bit of duplication
Thanks to Bas Scheffers for suggesting changes here!

If you start multiple ASIHTTPRequests from different threads at the same time, you could encounter a condiition where networkThread is being multiply initialized

need to use NOT NOT maxBandwidthPerSecond instead of (maxBandwidthPerSecond). Otherwise value like 1024 will be false
