Update ElixirLexer and example_elixir.ex

Elixir syntax has evolved quite significantly since the initial lexer
was written. In this update I have rewritten most of the code to support
modern Elixir (as of v0.14.0-dev).

The example file has also been updated to give an quick overview
of most of the language constructs.
