Incompatible with Guard 2.0 (was: guard init elixir failing)

[DevL]

UPDATE Locking guard to a version below 2.0 made things work again.

UPDATE 2: There seems to be a fix in https://github.com/os6sense/guard-elixir but unfortunately that hasn't been submitted as a pull request to the upstream (this) repo. @os6sense - would you be willing to either submit a pull request or be open to wokring on a proper successor fork with updated gems posted to Rubygems?

Steps to reproduce:

1. Add guard-elixir to the Gemfile
2. bundle
3. run guard init elixir

$ guard init elixir
10:42:48 - ERROR - Could not load 'guard/elixir' or '~/.guard/templates/elixir' or find class Guard::Elixir
10:42:48 - ERROR - Error is: No such file or directory @ rb_sysopen - /Users/devl/.guard/templates/elixir

This would be nice to resolve
