Improve target temperature selection logic

Browse Source 
When picking which of the high/low temperatures to display as the
"target", it makes more sense to take the outside temperature into
consideration, rather than the current temperature of the thermostat.

If the temperature outside is less than the temperature of the
thermostat, then we are far more likely to end up in "heating" mode
eventually, and vice versa, regardless of where the current inside
temp falls in the range between high and low.
