Add a sun cream tip for hot days (high > 26°C)

Browse source 
Temp-based stand-in for the UV-index idea from earlier -- neither
provider is currently fetched for UV, so this reuses the same
highTemp value already computed for the jacket tip, just the other
direction. Mutually exclusive with jacket (a high can't be both
<12 and >26).
