Add grunt task to build `flashmediaelement.swf`
Add task to build the CDN version of flash file
Add grunt task to clean the `local-build` folder
Remove older version of the build scripts
Add task to remove console.log (see #1147 & #1243)

of IE, the `console` object is only created after opening the
