Our docs show platform-getting-started and plugin-development guides for a variety of platforms. A few of those are already officially deprecated by Cordova (such as blackberry10 and WP8). Some I think are unofficially deprecated (ubuntu).

I think we should:
a) remove or at least make clear in our docs the platforms that are deprecated/removed
b) reflect any needed changes on the website (http://cordova.apache.org/#supported_platforms_section)
