ups.rb update to support getting multiple service quotes instead of just one like price.

ups = Shipping::UPS.new :zip => 97202, :state => "OR", :sender_zip => 10001, :weight => 2
    
ups.rate => [["UPS", "08", "worldwide_expedited", 134.55], ["UPS", "65",
nil, 158.05], ["UPS", "11", "standard", 35.22]]

This patch is dependent on the base.rb patch I submitted for Canadian postal code   lookups.

Thank you for providing this patch!  It's really nice to be able
to get multiple rates.  It's working perfectly.
