tiapp.xml & npm prompt update

Had the following issues when running the project

program.prompt is not inside commander anymore, so I've included prompt (cli/tishadow): https://github.com/tj/commander.js/blob/327a3ddd552f90d1dbd37f55fa7a88b9553468ae/changelogs/CHANGELOG-2.md#200--2013-07-18
when building the app it still had the old 7 SDK inside the tiapp.xml and there was this error unexpected element <uses-library> found in <manifest>. :arrow_right: updated SDK version and remove the uses-library part. Think it is for samsung multiwindow
