> For CB-9617, a change was made to automatically do a 'cordova prepare' 
> operation after adding every plugin. As part of the prepare, all the files 
> from the project's www directory are re-copied into the platform_www 
> directory. For a large project with lots of source files, images, and other 
> resources, this copy operation is potentially time-consuming. And it is 
> redundant and unnecessary when adding a plugin, because those files do not 
> need to be changed when adding a plugin.
> For a large project with many plugins, this slow redundant operation is 
> repeated for every plugin, making the first-time build (installing all the 
> plugins) take a very long time. As an extreme case, a customer reported their 
> large project (35 plugins, ~150 MB in www) takes about 2 hours to build the 
> first time. Most of that time is spent repeatedly preparing the platforms 
> after adding each plugin. The log line that appears to be slow says it is 
> "Generating config.xml from defaults for platform <platform>", but what it is 
> actually doing is redundantly copying lots of files from www.
> This issue can also be observed at a smaller scale when building the Cordova 
> mobilespec project, which contains tests for all the core plugins.
