client: Simplify screen selection decision tree.

This commit remove the `awful.tag` "manage" hook. The relevant
code has been moved to ewmh.lua request::tag handler. The handler
is called either by a volontary screen change or by a forced one.

It also require the awful.rules to be executed. This is done by
default and the user would have to explicitly disable that
behavior. From now on, disabling the rules require the user to
handle tag selection.

Fixes #1028 #1052
