Added backwards compatibility to `users.c', so I can use `utmp' too if `utmpx' is not found.
Added checks for `utmpx.h' and `getutxent' to the configure script
Now using utmpx instead of utmp in users.c to be POSIX 1003.1-2001 compliant.
First version of the users plugin.
Corrected the default prefix in `INSTALL'
Added information about cpufreq to ReadMe and manpage
Changes debian package to build with the new path settings
RRDs and PID file are now underneath `localstatedir'
Fiddling with that autoconf/automake stuff..
Merged Niki's changes to `collectd.h' to trunk/
Moved files into standard directory structure
