Allow to enable/disable functionality

KevinVb → made their first commit to this issue’s fork.

Added the options to disable the modal. An option for menu, term and media is available.
I've chosen for the disable option so backward compatibility is easy, if nothing is available or configured the module will just function as is.

Tested the enable/disable feature provided in @KevinVb's MR. It works well for me. We can now enable or disable this functionality for menus, terms, and media as needed. Moving this to RTBC. Thanks!

I was missing the check in the local_actions_alter. So added those. Will need re-testing.
