debug var
skip all the generating stuff when gen() is called with null as route and no parameters. good for attaching fragments to the current url or changing the hostname etc
fixed ugly chars getting encoded during constants replacing and thus making DOM bark. also won't replace in fragment identifiers anymore, but that wouldn't make a difference I guess
another fix :)
replace '&' in gen() url if necessary, fix for issue introduced in 1aa411e10ade75b2dba8a0a646802cdad236a0e0
allow 'container_parameter' source for caching groups, call toString() if a given group is an object
fix wrong phpdoc
