munin-node.conf can be used unmodified for lenny
add apache site
adapt to new "common" module
use cidr_allow in lenny and newer

This change keeps munin_allow for etch and feisty, since I don't know whether
cidr_allow is already possible there. Everyone else should change to the much
nicer CIDR notation of cidr_allow.

You can use an array to specify multiple rules.
Add initialisation for munin.conf.header
remove superfluous graph_period specification
Remove superfluous modules_dir/.ignore and fix README
Move interfaces fact to munin_interfaces

This is to avoid clashes with newer facter versions which bring
their own interfaces fact.
avoid passing on the superflous @... suffixes on interfaces
some clarifications to README for those who do not have the empty directories
move plugin directory to fit new 0.25.x style and update file paths accordingly
adjust README to note the new munin_cidr_allow variable
fixup the README so it includes DavidS' changes for the munin_cidr_allow information:

* add back the cidr notation to the example variable
* add back the information about pre-lenny versions
take out the removal of the postfix_mailvolume munin plugin. I do not see what the bug is, and this interferes with local installation of the plugin (causes duplicate definitions)
