Title: Fixed IIS fields and enabled stats in Kibana for numeric fields

hyphen in fields isnt allowed and elasticsearch was showing stuff like 'time' rather than timetaken.
mutate block was added as it enables statistics for numbers in kibana (per this thread http://comments.gmane.org/gmane.comp.sysutils.logstash.user/1759 )
