Need to provide specific API that will be useful for both CordovaSim and AeroGear

• find all plugin.xml files in the "plugins" dir and create List of plugins for the specific platform (Android, ios etc.)

• generate valid content of the cordova_plugins.js

• change plugin's .js files by wrapping their content into the function
  adds "cordova.define( pluginId, function(require, exports, module) { .....}

  etc.
