Module route plural paths & names

[solomon-ochepa]

Based on https://github.com/nWidart/laravel-modules/issues/949

• Added two new replacements - PLURAL_LOWER_NAME and PLURAL_STUDLY_NAME
• Generate modules route path in a plural name (e.g. /users, /posts, etc.)
• Allow the route resource to auto-generate its name from the path.
• Added the a new replacement to the config file

thanks but this will break people's projects that don't have the new key names in their config. I don't think this is needed.

This feature is needed, however you are right about it breaking existing projects.

I'll add a fallback key and apply for reopening.
