Added feels like and wind gust to 3 day forecast data.

Including feels-like and wind gust icons.
Added UV Index icon to forecast data
Add UV icon files
Regional update interval is twice a day
Rename and make updatefrequency more json-like
Update api args with location_id instead of coding in a function call
Back to individual parser functions

Went back to individual parser functions because the mega function
was getting unwieldy with lots of conditionals for special cases.

With individial parsers the skinning should be simpler too.
Simplify Regional Forecast parsing
Simplify daily forecast

And make sure it produces data that can be understood by the
default skin.
Simplify 3hourly report
Put precipitation percentage in script, not skin
remove print statment
use createdOn instead of issuedAt

issuedat is sometimes in the future! O noes robots! pewpewpew!
More descriptive logging
Add timeout otherwise urlopen will hang
lower() wind icon so file can be found without case error
rename because we're not always returning a forecast
Reorder. Because pretty things are pretty.
Location (as used in "Current" panel) is actually an Observation Location

So lets tell the truth. Also remove Current.Location because this is
never used.
Lower case na, otherwise KeyError or file not found
