Normalizer phone number

The program improve the phone numbers of the format 89 in the format of +79/

Remove from phone number all that is not a digit or +.

Perhaps replace part of text in all phone numbers.

Before use, I recommend to copy all contacts.

For some of contacts change is not possible.
