"userdir" caching scope: use it for userid lookup caches, reduce code duplication For same reasons (see previous changesets), we need to use the "userdir" scope for the name2id / openid2id lookup caches, too.

Purpose:
========
This script allows you to globally delete all the cache files in the directories:

* <data_dir>/pages/PageName/cache/
* <data_dir>/cache
* <user_dir>/cache

You will usually do this after changing MoinMoin code, by either upgrading
version, installing or removing macros or changing the regex expression for dicts or groups.
This often makes the text_html file invalid, so you have to remove it (the wiki will recreate it automatically).

text_html is the name of the cache file used for compiled pages formatted by the wiki text to html formatter.

Detailed Instructions:
======================
General syntax: moin [options] maint cleancache

[options] usually should be:
    --config-dir=/path/to/my/cfg/ --wiki-url=http://wiki.example.org/
