Improved candle-lighting times

We've switched candle-lighting times to use an NOAA (National Oceanic and Atmospheric Administration) algorithm. Candle lighting times are now a minute or two earlier and now agree with the Hebcal for C version (and with most popular sunset calculators).

This release also changes the default formatting of candle-lighting times to use 12-hour clock (e.g. 7:34pm instead of 19:34) for locations in the following countries: US, CA, BR, AU, NZ, DO, PR, GR, IN, KR, NP, ZA
