Added missing “use sigtrap”

Stop leaving locks behind
If you want to leave the thing locked when it is suddenly stopped (that is, interrupting the process will lead to bad consequences, and the admin should get in and make sure that everything is ok), then use **0**. **0** (or other falsie) means do nothing if it is suddenly interrupted and leave the lock in place. **1** means that your lock will be removed automatically if the whole thing is interrupted in the middle of the process. ##CleanLock('yourlock')## function will be called, which means that you can add your own cleanup logic by wrapping this subroutine (which I did in Modlue:private-wiki.pl).

-=head1 Preview Extension
-
-This module allows you to preview changes in HTML output. Oddmuse keeps a cache
-of the HTML produced for each wiki page. If you install new modules, the HTML
-produced for a page can change, but visitors will not see the new HTML because
-the cache still contains the old HTML. Now you have two options: 1. clear the
-HTML cache (Oddmuse will regenerate it as visitors look at the old pages), or 2.
-edit each page in order to regenerate the HTML cache. What happens in practice
-is that you add new modules and you aren't sure whether this breaks old pages
-and so you do don't dare clear the HTML cache. Let sleeping dogs lie.
-
-The Preview Extension produces a list of all the pages where the cached HTML
-differs from the HTML produced by the current set of modules. If you agree with
-the new HTML, feel free to clear the HTML cache. That's the point of this
-extension.
