Cheap fix for permission issues

Problem:

When trying to expand variables you may encounter a permissions issue with the topic and become unable to save the new expanded version of the topic.

Solution:

The issue might be because the previous topic write sets access control on the topic (if specified in the template) which prevents plugin from writing to the topic again.

A dirty solution is to find this snippet of code in NewUserPlugin.pm

    $errorMsg = Foswiki::Func::saveTopicText($usersWeb, $wikiName, $text);

and change it to this

    $errorMsg = Foswiki::Func::saveTopicText($usersWeb, $wikiName, $text, 1);

the addition of the 1 tells the saveTopicText function to not check permissions when writing.
