Impossible to Quote Envelope

In its current form, this module requires that weights be an integer. However, fedex defines envelopes as less than 0.5 lbs. Therefore, it is impossible to ever quote an envelope. A patch is needed to change line 555 to this:

"'Value' => ceil(($package->shipweight * $weight_conversion_factor)*100)/100,"

This will allow you to specify weight to the hundredths and calculate envelope shipping costs.
