Pull #37

travis-ci

Remove support for Elixir 1.3.2

Do this because credo 1.0.0 has moved to >= Elixir 1.4.0
For Elixir 1.3.2, running `mix credo` in travis ci yields the following
error:

```
Generated credo app
Checking 45 source files ...
** (UndefinedFunctionError) function Enum.split_with/2 is undefined or private. Did you mean one of:
* split/2
* split_while/2
