[collectd] New webpage - wiki too narrow

[Mariusz Gronczewski]

Hi,

on some pages of wiki like
http://collectd.org/wiki/index.php/Plugin:IPTables (last graph)
http://collectd.org/wiki/index.php/Plugin:DBI (text getting on textbox
with plugin list)
http://collectd.org/wiki/index.php/Plugin:cURL (same as above)
and all pages with any type of graph (graph is pushed down below
plugin list creating big empty space) wiki is too narrow and it don't
look nice.

Regards
Mariusz
