Change ouibounce library structure to allow npm-asset / bower-asset installation

@Grevil could you do this?

Don't do more than needed. For example please no more complexity with production / dev switch etc. - keep it simple. But ensure it doesn't break for existing installations without being notified.

Thanks :)

Done and tested.

Here is the output of the update hook:

 ---------------------- ----------- --------------- --------------------------------------------------------------------------------------------------------- 
  Module                 Update ID   Type            Description
 ---------------------- ----------- --------------- ---------------------------------------------------------------------------------------------------------        
  ouibounce_exit_modal   9001        hook_update_n   9001 - IMPORTANT. The path to the ouibounce.js has changed from "/libraries/ouibounce/ouibounce.js" to
                                                     "/libraries/ouibounce/build/ouibounce.min.js", also note, that the "ouibounce.min.js" file is used now,
                                                     instead of the normal "ouibounce.js" file.

GREAT work once again @Grevil! :) Smart!

As we'll need a new branch for the BC in 🐛 Render block entities, not plugins unless all plugin settings can be configured Needs work anyway, I'll do that tomorrow and merge into 4.x!
