This change allows for easy customisation of the relation manager titles and toolbar buttons.
For buttons - define your custom strings directly in the standard `toolbarButtons` syntax...
```
toolbarButtons:
create: acme.blog::lang.subcategory.CreateButtonText
delete: # omit the string to fall back to the default button text
```
...and the old syntax still works...
```
toolbarButtons: create|delete
```
For titles - define different strings for each mode (form, list or pivot)...
```
title:
form: acme.blog::lang.subcategory.FormTitle
list: acme.blog::lang.subcategory.ListTitle
```
This feature provides developer convenience, for example in this situation where I have a relation manager that is used to assign user permissions to a project:

This PR contains no breaking changes.
Credit to @tobias-kuendig. Added $.oc.relationBehavior.changed function. To keep track of changes made using the relation controller this new "changed" function is called every time a record is created, added, removed or deleted. The function triggers the change.oc.formwidget event on the form field that belongs to this relation controller so other form fields are notified about the changes.
