Add possibility of having project files in different locations than root, when packaging webos project

[ejbp]

Add possibility of copying subdirectories into our project

ex [package.json]: "react-tv": { "files": [ "./public/index.html", "./dist/bundle.js", "./dist/assets/" ] }

./public/index.html file will be copied to [webos_project_root]/index.html ./dist/bundle.js file will be copied to [webos_project_root]/bundle.js ./dist/assets/ dir and it's content will be copied to [webos_project_root]/assets

note 1) in this change, .npmignore was not implemented

note 2) If you add a directory that stand on the root, it will not work. ex:

"react-tv": { "files": [ "./public/index.html", "./dist/bundle.js", "./dist/assets/", "./videos/" ] }

This was not implemented cause may cause corruption of our default webos_project files, like appinfo.json or even the [].ipk file itself. Problem it could be implemented when the .npmignore.

Hi @ejbp, I don't know if this is the best approach for solving it. Related issue to #110 #111
