Use Firebase as Cloud File Storage

[rodriggochaves]

Since amazon isn 't simple to create a development enviroment (your AWS account should be newer that one year), I believe that we should use Firebase as alternative. New developers can contribute easier.

I think we can begin to develop some API to the Storage module. We can achive this by using Elixir's Behaviour, then we can do something like this:

defmodule Storage do
  @callback upload_repo(String.t, String.t) ::  {:ok, term} | {:error, term}
end
