Fix to issue 82(cordova-plugin-app-preferences.platform already defined)

[pcbl]

Fixing issue 82, where the following error was showing on windows apps: 0x800a139e - JavaScript runtime error: module cordova-plugin-app-preferences.platform already defined

Basically, on lines 90 and 97 you have something like this:

90: <js-module src="src/windows8/platform.js" name="platform"> 97: <js-module src="src/windows8/platform.js" name="platform">

The problem is that, as you can see, the name "platform" is being used. And later, during the cordova_plugins.js generation, it turns out that this name is already taken by the main platform agnostic javascript:

Platform agnostic one(plugins/cordova-plugin-app-preferences/src/platform.js):

    {
        "file": "plugins/cordova-plugin-app-preferences/src/platform.js",
        "id": "cordova-plugin-app-preferences.platform",
        "pluginId": "cordova-plugin-app-preferences"
    },

Platform specific one(plugins/cordova-plugin-app-preferences/src/windows8/platform.js):

  {
        "file": "plugins/cordova-plugin-app-preferences/src/windows8/platform.js",
        "id": "cordova-plugin-app-preferences.platform",
        "pluginId": "cordova-plugin-app-preferences",
        "merges": [
            ""
        ]
    },

That triggered the error!

With that in mind, I got it fixed, at least temporarily, by changing my plugin.xml to something like this:

90: <js-module src="src/windows8/platform.js" name="platform.w8"> 97: <js-module src="src/windows8/platform.js" name="platform.windows">

Once I have done that, the cordova_plugins.js was generated without the duplication!!!

Platform agnostic one(plugins/cordova-plugin-app-preferences/src/platform.js):

    {
        "file": "plugins/cordova-plugin-app-preferences/src/platform.js",
        "id": "cordova-plugin-app-preferences.platform",
        "pluginId": "cordova-plugin-app-preferences"
    },

Platform specific one(plugins/cordova-plugin-app-preferences/src/windows8/platform.js):

  {
        "file": "plugins/cordova-plugin-app-preferences/src/windows8/platform.js",
        "id": "cordova-plugin-app-preferences.platform.windows",
        "pluginId": "cordova-plugin-app-preferences",
        "merges": [
            ""
        ]
    },

Hi, thank you for the patch. This is definitely cordova bug: windows and windows8 is different platforms and only one platform.js is needed. I'll accept your patch but I need to investigate little further to make sure everything works fine.
