Added nuGet scripts and removed old skeleton files 

1. Added shortland `nodejs` script for for `pack` and `push` the `nuget packages` (for now just durdandal.nuspec)
This is useful if you want to test the nuget package on your own nuget feed servers but don't deploy it to the nuget live server feed just yet.
#### Note
Optionally you may want to define a file `apiKey.txt` and define on each line your own repositories and keys such as 
`-Source http://nuget.owndomain.com YourApiKey`

2. Deleted old skeleton files that remain after the last pull request / merge
