Adding two new parameters:

; if set to 1, only requests done in CLI mode (eg. the archive.sh cron run) will be logged
log_only_when_cli = 0
; if set to 1, only requests with "&debug" parameter will be logged
log_only_when_debug_parameter = 0

this will make lot easier to enable debug and not mess up everything (eg. on the demo, or if piwik is heavily used by other concurrent users or via the API)
