    Add functionality to install modules during init (#233)
    
    * Add functionality to install modules during init
    
    Install modules specified in package.json during initialisation as a 
alternative to packageing them.
    Detect if the node_modules directory is  missing and installes the node 
modules.
    
    * check if package.json has dependencies and install if required
    
    * remove trailing whitespace
    
    * read package.json correctly as object
