Auto trailing slash path variable

New feature

We’ve added a new {path:auto_trailing_slash} destination variable to be used in your destination. This variable automatically adds a trailing slash to the end of the variable value, if the path itself doesn’t end with a trailing slash, and the last segment doesn’t contain a dot (i.e. isn’t a file extension). This can be used for niche use-cases, where the destination always requires a trailing slash.
