Day Boundaries are wrong

[djcapelis]

Currently Chimery always puts things in the current day, should probs switch to doing QDateTime everywhere instead of using currentDate + QTime. It'll be better because it'll be doing things correctly instead of the hack you have in there for no good reason now. Yay!

(This currently means the app doesn't work at all between 23:55 and 00:00 and means that it doesn't work super well when you try and set it for a time in a future day.)

(You could also do a complete hack and make sure that any timepoints that are already past are put into the next day, but you'd want to make sure that you infer correctly, since timepoints that already past could totally happen if someone triggers a schedule a few minutes after they set it up.)
