logtool. and lots of things in the main firmware.

better integration into main
fixed scheduler and timestamping
simplified the api there
ditched integer 64-bit storage types (not needed. 32 bits is plenty for everything except current time - but that's handled in RTC, everything else is deltas)
web remote!
