Plugin: parenttag

This plugin deals with subtags (e.g. `mathematics/calculus`

). Whenever a page is tagged, it is automatically tagged with its subtags as well: the following directives are equivalent:

```
[[!tag mathematics/calculus]]
[[!tag mathematics mathematics/calculus]]
```

The `taglink`

directive is changed as well: instead of displaying the leaf of the tag, the full path (up to `tagbase`

configuration option) is displayed, each bit linking to its corresponding page. For instance, directive `[[!taglink mathematics/calculus]]`

creates a link similar to `[[TAGBASE/mathematics]]/[[TAGBASE/mathematics/calculus]]`
