powersaving interval script for sx220 with logging

It took some effort to find a suitable script for the sx220 (without optical view finder) for timelapse with powersaving. When i finally found one, it had no posibillity to write data (battery voltage and temperatures) to a logfile, so i used the script and added a logmode. Enter a number for logging in the menu and this becomes the logfile number log_<nnnn>.txt. The logfile can be easily read into a spreadsheet to make graphs of the results. I altered the script kept the original writers in the header and added myself. Maybe somebody can use this script as well, thats why i share it. Its tested on the sx220, but will probably work on many other types.

The logfile looks like this:
dd.mm.yy  hh.mm.ss,#frame,Vbattery,Toptical,Tccd,Tbatt

Upload them to imgur.com and then cut and paste the BBCode link from there.
