#132 Minor improvements to RecentChanges plugin

[Matt Brown]

This patch fixes two minor problems in the
RecentChanges plugin.

The first prevents the getArgs function from defaulting
to the HTML formatter on action pages if the user has
already explicitly specified an alternative formatter
they would like to use.

The second sets nofollow on the date links on the main
RecentChanges page to prevent unnecessary google indexing.

This patch is part of our attempt to merge the WLUG
Wiki source back into PHPwiki. It originates from
http://svn.wlug.org.nz/viewcvs/trunk/lib/plugin/RecentChanges.php?root=wiki&rev=43&view=diff&r1=43&r2=42&p1=trunk/lib/plugin/RecentChanges.php&p2=/trunk/lib/plugin/RecentChanges.php
