Deprecate core.use_routing in favor of a routing config parameter

[david]

It always runs, anyway. But the actual idea is that you could then switch routing off for, say, the CLI context (which means it falls back to $argv or whatever instead of using parsing magic), but keep it on for web:

<routing class="AgaviConsoleRouting">
  <parameter name="enabled">false</parameter>
</routing>

The calls to this would look like the following:

$ro->getParameter('enabled', AgaviConfig::get('core.use_routing'));

So we have full BC. Maybe even a dedicated method? It's not used outside the routing classes, either.

There's AgaviRouting::isEnabled() now, btw.
