Initial work on adding a requester of USB permissions

I was able to include the permission XML that allows any app to "respond" to a just-plugged printer, but......... not more than that. Any Java code I included (even blatantly broken stuff) never caused an issue during compilation or runtime, not more than the current bug causes. No clue how to actually compile the plugin and get it into the debug app. This is supposed to be a solution for auctifera-josed#58

 Cordova plugin for using [Star micronics printers](http://www.starmicronics.com/pages/All-Products) from a cordova, phonegap or Ionic application.
 
+> This fork was made to solve [issue#58](https://github.com/auctifera-josed/starprnt/issues/58), where in some scenarios, Android apps would crash because of missing permissions.

 ## React Native Version ➜ [here](https://github.com/infoxicator/react-native-star-prnt)
 
 **Note:** This is based on the work from the guys at [InteractiveObject](https://github.com/InteractiveObject/StarIOPlugin)
