Title: Add support for %w and %W (words) sigils

Lists of binaries are incredibly common and introduce a lot of visual noise:

```elixir
["о","п","т","и","м","и"," ","з","а","ц","и","и"]
```

Word sigils are for lists of files, command line options, and much more. Doing a `grep -R "\[\"" * on the Elixir source will give you an idea of where %w could cleanup the code.

``elixir
File.join %w( etc apt sources.list )
OptionParser.parse_head(%w[--source lib test/enum_test.exs --verbose])
%w( words
are
great )
