For locks and getRevisions there hasn't been any acl check. In many
other cases the id hadn't been cleaned before the acl check was done
which means that many acl rules that should be applied weren't applied.
So e.g. when you have read permissions for the root namespace but not
for a subnamespace you could add a leading ":" and the permissions for
the root namespace will be used instead of the permissions for the
subnamespace. This did not apply to writing pages and reading media
files, but writing and deleting media files have been concerned as well
as reading both plain and html versions of pages.

This only concerns installations where XML-RPC is enabled (default is
disabled) and XML-RPC is allowed for all or untrusted users.

This makes it possible for plugin and template authors to overwrite or
extend the quicksearch JavaScript logic.

This patch moves the shortening of namespaces in the quicksearch results
to JavaScript. This makes it independend from used template and will
always try to fill the width of the result pane correctly.

Things missing:

  * Make it work with RTL-languages
  * Check Browser compatibility (only tested in Chrome so far)

- better use of Latin terminology for DokuWiki
- ACL is not translated as AAA (Aditus Administrationis Aditus) but
  with ICA (Index Custodiae Aditus), which is a more literal translation
- minor corrections of grammar and logic
- The word "namespace" is more literally translated "spatium
  nominis", but according to other translations (like the Italian one),
  I preferred to use "genus".

As suggested by Robin Getz locale .txt files can now be duplicated and
changed in the conf/lang/ directory and conf/plugin_lang/$plugin/
directory for plugins.

This reverts commit 48714142.
Additionally there is a new fix for FS#2107 that doesn't introduce a lot
of checks but instead ensures that the configuration option can't be set
to negative values when the configuration manager is used.
