Old version of twig incompatible with timber

Hi Happy,

The version of twig (1.24.1) embedded in zip recipes is old and causes a fatal error if you activate zip recipes on a site that uses a timber based theme since timber is using a more recent version of twig (1.31.0).

I was able to fix this problem by simply replacing the vendor/twig/twig directory in Zip Recipes with version 1.31.0 of twig downloaded from the twig github page: https://github.com/twigphp/Twig/tags.

You may want to consider updating twig in the next release of Zip Recipes.
