Make routes to rewrite configurable with settings page

Hi Andrey Proh,

I added dependency injection and added the validateForm method to check if the routes the user insert exists.

Correction to use existing routes from configuration.

Patch fix, for 2.0.0 using existing config.

I am closing this issue because we have recommended release 2.0.1 - which contains this feature.
