This patch adds /usr/lib/nsplugins to the search path for plugins.  Note that
mozilla/firefox/thunderbird/seamonkey handle dup plugins like this: First by
mtime order (more recent takes precedence), second by alpha order.

The point of this patch is to provide a place to install netscape-compatible
plugins which can be used by any of mozilla/firefox/thunderbird/seamonkey, for
example the acroread plugin.  This obviates the code in nsplugins.eclass except
for inst_plugin
