Phonenumbers

* Code changes
- Making the application of alternate formats when finding phone numbers in
text in strict-grouping and exact-match mode depend on the leading digits
for each rule. This was always assumed but never actually done. This means
that the false positive rate will decrease but also that more valid numbers
are skipped. A subsequent CL will update patterns to increase recall.
