Title: With the new elixir.bat version the batch script only worked from the ./bin folder on windows

Apparently, when shifting parameters, the %~dp0 is not preserved,
so it needs to keep this value. This will fix things like iex on Windows, which just crashed with the version I just committed; my apologies !
