Exception handler move to a service

[tyx]

Let people more easily override the exception handler.

[stof]

Renaming the config and the service is a BC break.

and I don't understand the reason of this change. the exception handler is already a service

[tyx]

Yes BC Break I know. For now I have no idea to avoid it.

It is already a service but you can only change the class name or I miss something.
So it is not really a service as the view_handler which can be totally overrided by users.

yes, I fear you will need to add some BC code to ensure that the old and the new settings still work, throwing an exception in the extension if both are used at the same time. also the tests need to be fixed/expanded accordingly

[tyx]

I will do.

[lsmith77]

please also rebase on master so that the travis setup works again.

[eduardosoliv]

👍 I already had the need to inject stuff on the exception handler

[lsmith77]

someone just needs to wrap up the last details

[tyx]

I hope I have time this week
