Bug 5610 Script to force borr transport defaults messaging

If the EnhancedMessagingPreferences syspref is enabled after borrowers
have been created in the DB, those borrowers won't have messaging
transport preferences default values as defined for their borrower
category, even no transport preferences at all. So you would have to
modify each borrower one by one if you would like to send them 'Hold
Filled' notice for example.

I propose this script to create transport preferences for all existing
borrowers and set them to default values defined for the category they
belong to.

[DOC] Should be documented somewhere.
