[collectd] "Redesign" of the Debian collectd package

[Mariusz Gronczewski]

Hi,

one more thing about collectd package. Atm (at least in testing) when
u purge package it removes all rrd files from /var/lib/collectd, so
when for example (like i did on one of my servers) u want to compile
ur own version (coz u need plugin x or function y and ure using stable
whch dont have it) and u remove collectd package all data is gone
(good i had backups ;]), it should ask like some other packages "do u
want to remove statistic data also" (i think mysql and dokuwiki have
something like that)
