Merge branch 'fixlog' into json

Conflicts:
	common/lib/Munin/Common/Logger.pm
json: retrieve the attributes
json: use direct attributes
json: adding the id selector to the url
json: adding group handling
json: adding ds handling
json: adding basic filter abilities
master/sql: add the DS states in the SQL db

And it is compatible with the future standalone Storable2SQL tool
json: add state support
