Bug 16621: Translatability: Issues in opac-user.tt (sentence splitting)

This patch fixes issues due to sentence splitting in
koha-tmpl/opac-tmpl/bootstrap/en/modules/opac-user.tt

Note: This is a string patch. It does not add or change functionallity.

To test:
- Examine code and verify that the text changes remove sentence splitting
  and that the changes make sense.
- Log in to OPAC and verify that messages look correct
  - with blocked /debarred user (with and without comment and date)
  - with user who has to much fines (needs syspref OpacRenewalAllowed
    and syspref OPACFineNoRenewals)
  - with user who has his card marked as lost
  - with user with an account that is about to expire
  - with user with expired account
  - with user with uncertain address information (with and without
    syspref OPACPatronDetails set to Allow)
