Introducing OneSky Forecast!

Yeah, we messed up. We had been using "Astronomy" for all our products for 20 years and never thought for a second that calling something "Astronomy Weather" would be more overloaded than terms like "3D" and "AI" (okay, maybe not that last one).

So, starting today, Astronomy Weather will now be known as OneSky Forecast! That's right, same product, new shiny, potentially more SEO-friendly name.

Version 1.0.4 has just been released with multiple updates due to your helpful feedback:
- Corrected Support and Help URL's for Windows installation.
- Added a message to the locations lookup screen when the API key is invalid.
- Removed preferences.json by default. Only create if it doesn't exist. Should avoid overwrite on upgrade.
- AQI: Reduced description length.
- AQI: Added color coding to each pollutant to give more indication why the AQI level is where it is.
- Preferences: Refresh no longer allows a more aggressive update time than 10 minutes to avoid capping out API usage requirements.
- Performance: API's now load asynchronously, improving load times.
- Reliability: In situations where certain views do not get data in time, the previous data remains instead of appearing blank.

Today, we just released version 1.0.3 with the following updates:

- Temperature Values: Changed "-0" readings to appear as "0".
- Pressure: Changed "Normal" to "Norm" to take up less space on the view which can force truncation of the graphic.
- Hourly Forecast: Fix consistencies with AM / PM text in ARM mode.
- Sun/Moon: Align 6AM, 6PM to be closer to graphic when stretching horizontally.
- Preferences: Fix formatting to match "Locations" and "About Us".
- Multiple Views: Hide Text-based ToolTips in Pi mode. They are more distracting than helpful.
