documentation on Events and @HasLifecycleCallbacks annotation

[dao]

docs/en/reference/events.rst claims that @HasLifecycleCallbacks annotation is required to indicate that a Document has .. lifecycle callbacks. I grepped "HasLifecycleCallbacks" in my vendors directory and only got results from ORM.

Is this annotation actually necessary?

This is related to #428. @HasLifecycleCallbacks was removed and we were discussing adding it back, as there were issues with method annotations triggering twice within inheritance hierarchies. I'll try to get that issue resolved soon.

[bmeynell]

Can we use lifecycle callbacks in ODM without this?

[gui-com-pt]

@bmeynell yes, you can

[jmikola]

@dao: #428 was resolved, so I think this can be closed.

I believe there might have been some confusion since the docs were published from master before the release itself was tagged.

@bmeynell and @guilhermegeek: The @HasLifecycleCallbacks annotation is required for lifecycle callbacks as of BETA10. See the changelog for a more detailed explanation.
