iOS / asi-http-request

ASIFormDataRequest has a default 'GET' method (should be 'POST' by
default)

* Ensures external resource requests are properly removed from the queue and released when they fail
* Changes behaviour so that by default, external resource request failures do not cause everything else to fail

Also added new shouldIgnoreExternalResourceErrors property to control this

closes gh-241

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 CopyWithZone method did not copy the authenticationScheme, resulting
in problems when using a copied ASIHTTPRequest.
