Adding helper to reload elixir modules while in iex.

[khia]

Typical usage scenario is like follows:

    iex(1)> use Reload
    []
    iex(2)> reload [My.Awesome.Elixir.Module]
    [{:module,My.Awesome.Elixir.Module}]

shouldn't this be ensure_loaded instead?

What do you mean:

1. reload should be renamed into ensure_loaded. It shouldn't since reload also do purge so semantically it's more reload rather than ensure.
2. Instead :code.load_file we should use unsure_loaded. In this case regular erlang modules couldn't be reloaded. Since internally module is represented as atom with __MAIN__ prefix erlang means of reloading works just fine.
3. Instead of reload the one could use ensure_loaded.
