Hi, first thanks for your pull request!
But Travis is failing :/
To run the testsuite locally you have to run composer install within the module directory and then run ./vendor/bin/phpunit

To check coding standards run
./vendor/bin/phpcs --standard=PSR2 ./src/

And to fix them:
./vendor/bin/phpcbf --standard=PSR2 ./src/

Unfortunately I see problems with your code: The same issue as in zendframework/zendframework#5670

For example: Vendor\SomeModule\Controller\Index::index
Result:

vendor
vendor-index
vendor-index-index

Maybe we just need to alter https://github.com/hummer2k/ConLayout/blob/master/src/ConLayout/Listener/ActionHandlesListener.php#L101 to:

$handleName = strtolower($this->inflector->filter(implode('-', $actionHandles[$i])));

The larger priority gap could then be achieved by just multiplying the counter $j by 10.

What do you think?
