Release 1.0.0

Summary:

This release breaks some backwards compatibility
on some plugins where they improperly used strings instead of
booleans parameters. This release also includes osfamily
support for SUSE and FreeBSD.

Backwards-incompatible changes:

 - Plugins that use to accept strings now use booleans
   for a more consistent interface across the various plugins
 - The main collectd config file now only includes *.conf files
   to allow plugin specific files to be placed in the conf.d
   directory.

Features:

 - Add osfamily support for SUSE
 - Add osfamily support for FreeBSD
 - Add tail plugin
 - Add exec plugin
