* Switched to using OMD rather than manually compiling check_mk

* Added support for host tags and creating host groups based on these tags

* Allow local check_mk configuration to be specified in
/etc/check_mk/main.mk.local that is appended to /etc/check_mk/main.mk as
check_mk can do a lot more than is covered by this module
