- added check before bolus is attempted, if we have enough in reservoir (from local info, we don't query the pump,

while this might not always be 100% correct, it is updated every hour (if under 50 U and every 4h if over
50U and every 15 minutes if under 20U, so it should be accurate, information is not accurate only if you cancel bolus midway...
