Elixir: Fix triple-string, add support for Eex

Browse Source 
This adds support for the Eex templating that is used in the Phoenix
web framework. Eex files include HTML and Elixir code, and Elixir files
can include Eex in string literals marked with the `~L` prefix.

Additionally this unbreaks `"""` string literals, which did not work because
`"` was matched before `"""`
