Subject: [PATCH] Add pattern for matching filenames to the Liquid lexer
 (#1351)

The Shopify Liquid parser and the Jekyll Liquid parser treat the
argument to the `include` tag differently. Specifically, the Jekyll
lexer expects a filepath.

The existing Liquid lexer does not properly handle code written for the
Jekyll implementation. This commit fixes that by introducing a rule thet
matches against slashes, periods and alphanumeric characters.
