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.

@tomstrassner You could init the array with a capacity to be more memory efficient.
```
NSMutableArray *weatherHours = [NSMutableArray arrayWithCapacity:[hourlyForecastDict count]];
```
