* feat: customMenus in footer
Show customMenu links also in footer.
In `config.yaml`,
- `params.footer.enable` is `true` to show the footer at all
- `params.footer.navigation.enable` is `true` to show navigation items
in the footer
- `params.footer.navigation.customMenus.enable` is `true` to show
customMenu items
Example:
```
params:
footer:
enable: true
navigation:
enable: true
customMenus:
enable: true
```
In `data/<language>/site.yaml`,
- `customMenus` must contain at least one entry with `showOnFooter:
true`
Example:
```
customMenus:
- name: Imprint
url: posts/imprint
showOnFooter: true
```
