Better handling of Classification/Property data from Hotlinks

[Katica]

No worries about Property and Classification data from Hotlinks. Smarter data handling reduces the module size, limits the number of actual “conflicts”, and saves you the work of checking them.

• A saved Hotlink module now includes only the Classifications that are actually used - this results in fewer “conflicting” data when you place the module as a hotlink

• Better info on potential data conflicts, with info bubbles to help

• Better info on differing data (between hotlink module and the host file), with info bubbles to help
