-In the last relase (0.7.x) we added two additional aliases `deps.get` and 
-`deps.update`. In this release, we added an alias for `run`.

-all the required aliases in the project `mix.exs`. We changed the pratice to

-`Nerves.Bootstrap.add_aliases/1`, however, this causes users who 
-did not have the `nerves_bootstrap` archive installed to be stuck in an error
-loop unless they would cd to a directory that did not contain an offending 
-`mix.exs` file to install the missing archive.
