Improve the `ngettext`-style functions to automaticaly add a `num` parameter, similar to [7423] on 0.11-stable.

Merged [7496] from 0.11-stable.

0.11-stable: Fixed "up" link for hierarchical pages to point to the parent page, and added an "Up" link to the ctxtnav for those pages.

Merged [7493:7494] from 0.11-stable.

0.11-stable: Added a notice to the "403 Forbidden" error page for unauthenticated users suggesting that the user should log in.

Closes #5340 as per [GoogleGroups:trac-dev:2e8be2a89307f7ce this message].

0.11-stable: Added an optional `referer=` argument to `/login` to specify the URL to redirect to instead of using the `Referer:` HTTP header.

This is the non-controversial part of the patch to solve #5340. The code was mostly copied from th:AccountManagerPlugin, which already implements this functionality.

This also fixes a small typo in `trac/web/href.py`.

0.12dev: Typo in de_DE translation (argument replacement).
