Item8344: TagMePlugin: Unable to allow everyone to change tags

In the documentation of TagMePlugin there is the following table about who's allowed to change tags:

Preference name	Meaning	Default
TAGMEPLUGIN_ALLOW_TAG_CHANGE	List of users and groups that are allowed to change (rename and delete) tags (names separated by commas). Users that are not allowed to change post their change requests to TagMeChangeRequests. If not set anyone can change tags.	AdminGroup

The way I understand it, using the setting

   * Set TAGMEPLUGIN_ALLOW_TAG_CHANGE =

(i.e. leaving it empty) in SitePreferences should allow everyone to change tags. This doesn't seem to work on my system. I first had to change TagMePlugin.pm:

     return 1 if !$allowModifyPrefNames;    # anyone is allowed to change

I'm not sure we want to unsecure by default, (seeing as its been admin group forever), but there is a need to be able to set it to something for a set of 'all registered users' - setting to WikiGuest should imo make it 'everyone'

In this case, the documentation is wrong as it states If not set anyone can change tags while it should say If not set only AdminGroup can change tags.

It should be enough to differentiate "undef" (not explicitly set, default to AdminGroup) and "defined, but false" (set to empty, allow anyone to change tags).
