* working on jsonwrapper
* finally, it compiles...
* 1st run without crashes
* query planer working
* cleanup old code

* fix also changing data collection frequency
* fix signess
* fix rrdlabels and dimension ordering
* fixes

* ml should accept NULL response from rrd2rrdr()
* number formatting fixes
