Issue with fetching UPS rates for Bermuda

[jamiemtdwyer]

This issue was forwarded from a partner:

The issue is this: When you try to get rates from UPS with Active Shipping using an origin address in Bermuda, it throws the following error:

Failure: This measurement system is not valid for the selected country

We believe that the root of the problem is line 128 or Active Shipping's UPS.rb file, which defines what it calls "IMPERIAL_COUNTRIES." That list does not contain the country code for Bermuda ("BM").

IMPERIAL_COUNTRIES = %w(US LR MM)

It seems the UPS API demands imperial units be used when the origin is Bermuda--at least adding "BM" to line 128 eliminates the error when fetching UPS rates with a Bermuda origin address.
