The translator defined a `meta` attribute, however:
* it was static so couldn't be expanded using the `meta` directive,
move to instance attribute, and create an `add_meta` method which
adds some indentation (for a cleaner HTML output)
* the `meta` directive itself was not supported by the translator
* turns out HTMLWriter just removes the first to entries of `meta` as
"cleanup", which explains why we had to duplicate it in the template
- therefore pad the `meta` list and remove entries from template
- move front to linktags, that seems more relevant
