Create the hook file

[rodrigograca31]

Hi!

With this plugin we need to manually create the hook file....
This other plugin is able to add the hook: https://github.com/rossmartin/cordova-uglify

1. It needs to be specified in postinstall in package.json https://github.com/rossmartin/cordova-uglify/blob/master/package.json
2. Then that script moves the file: https://github.com/rossmartin/cordova-uglify/blob/master/scripts/install.js

Also, you guys use ruby..... if possible it would be better if you guys used nodejs since it's more used...

Thanks!
