Bug 27812: Remove the ability to transmit a patron's plain text password over email

We should not give libraries the ability to compromise patron accounts,
it is considered a huge security issue and nobody in network security
would never recommend allowing passwords to be transmitted in clear text
over email.

It should simply not be possible to send a patron's password in plain text
via email. As such, we should remove this ability from Koha.

Test Plan:
1) Apply this patch
2) Create a patron to generate the ACCTDETAILS email
3) Note you can no longer transmit the patron's password in the email
