inheritance for computers

Currently the only way to configure inheritance for computers to child entities is to do it manually on each computer or to edit the MySQL database.

To set it for all newly created computers, you have to edit the MySQL database.

It would be cool to have a toggle in configuration to set it, and to be able to mass edit the computers to set it.
