Astronomy improvements

- Added model object for sun phase
- Added model object for moon phase
- Display raw astronomy data

Note: So many files changed because I had to change the class prefix from CL to CAE in all of the comments in every file.

Czech it out @rburr @blakecarrier @lukesteffen 
@tomstrassner I know it's just a log statement but it's good to get in the habit of being 64bit ready.

```
NSLog(@"Determining background color with temp:%ld, sunrise:%ld:%ld, sunset:%ld:%ld", [self.currentConditions.fTemp integerValue], [self.astronomy.sunriseHour integerValue], [self.astronomy.sunriseMinute integerValue], [self.astronomy.sunsetHour integerValue], (long)[self.astronomy.sunsetMinute integerValue]);
