Set up update.sh for vcs packages

Therefore, use $vcs_langs instead of $langs, due to fra-deu and deu-fra
missing in the vcs tree.

Furthermore, in
- svn/sample.PKGBUILD,
 `- change the default pkgrel to 2, since any update is forced, i.e.
    there is no version change asking for update;
- update.sh,
 `- add a usage note,
 `- require a specific type (e.g. src) to be supplied,
 `- remove the need to specify $ext for -u,
 `- set up a handle_all_vcs() function specifically for VCS sources,
    i.e. svn,
 `- move the download of freedict-database.json to handle_all().
