changed dependency versions due to elixir 0.14.2 problems

Just wanted to try out the framework a bit and had some issues when following your install manual. I am using Elixir 0.14.2 and there the function atom_to_binary seems to be removed. Due to that some of your dependencies does not work any more. 

Regarding this issue I changed some dependencies. But it came up the question to me why are you using fixed dependency versions? So by using {:plug, "~> 0.5.0"} instead of {:plug, "0.5.0"} I think this problem wouldn't have occured. 

Hope I could help you a bit and (@Chris) thanks for your coding session at Railsconv ;-)

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this

If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:
