Use Thor's apply instead of prerequisite tasks (#183)

The `javascript:install:shared` and `javascript:install:node_shared`
tasks serve only as prerequisites for the other installer tasks; they
should not be run on their own (nor listed with `rake --tasks`).  By
replacing those tasks with corresponding calls to Thor's `apply` method,
we avoid the overhead of running `bin/rails app:template` (and
`bundle install`) multiple times.

This commit also renames `install_node.rb` to `install_procfile.rb`
since it is concerned with generating a `Procfile.dev` file.
