NPM local dependency errors

[turicas]

Hello, everybody! First of all, thanks for this project -- it's helping me learn both Elixir and Elm. :)

I'm getting some errors when npm is installing local dependencies: it thinks the local dependencies (file:deps/phoenix and file:deps/phoenix_html) are actually GitHub dependencies (username file:deps and repositories phoenix and phoenix_html):

npm ERR! git clone git@github.com:file:deps/phoenix_html Cloning into bare repository '/home/turicas/.npm/_git-remotes/git-github-com-file-deps-phoenix-html-50a27b71'...
npm ERR! git clone git@github.com:file:deps/phoenix_html fatal: remote error: 
npm ERR! git clone git@github.com:file:deps/phoenix_html    is not a valid repository name
npm ERR! git clone git@github.com:file:deps/phoenix_html   Email support@github.com for help

I've tried changing to file:./deps/phoenix since the documentation give examples like this, but it didn't work:

npm ERR! notarget No compatible version found: phoenix@'file:./deps/phoenix'

To solve the problem I removed those lines from package.json, then run:

npm install
npm install ./deps/phoenix
npm install ./deps/phoenix_html

I know this issue is not directly related to the project, but prevents installing the dependencies correctly.

And since this project uses phoenix_live_reload you also need to run sudo apt-get install inotify-tools before running it.
I can work on a full installation (for whom don't have erlang/elixir/etc. installed) and create a pull request with updated README. What do you think?
