Instead of `client.client`, the client object is now referred to as
`client.object` and the client class as `client.class`.
This moves the documentation of `client.focus` to the class.
Closes https://github.com/awesomeWM/awesome/pull/349.
This adds a `stacked` boolean argument to `awful.client.visible`, and
(relevant) callers of it.
This can be used with e.g. `awful.client.swap.bydirection` to swap clients
based on their stacking order.
Fixes https://github.com/awesomeWM/awesome/issues/178.
This still does `client.focus = c` by default, but allows to customize
it.
This was initially suggested in #194, but by using `request::activate`
instead, which would not be the same. Therefore a new signal is being
used instead.
