Configurable taxonomy links

[chad-g-adams]

Right now it displays links for categories only. It would be nice to make this configurable so that other taxonomies such as tags (or new, user-defined taxonomies) may also be linked in a similar fashion. Furthermore it would also be nice to have an option to disable taxonomy links altogether.

I propose the following configuration option:

Links will be generated for these taxonomies

# Use to add links for categories, tags, etc.
# Example: [ "categories", "tags" ]
taxonomyItemsToLink = [ "categories" ]

I am starting on the code, will have a pull request available for review shortly
