Added ability to set coverage color based on status

[jasonuher]

Adds additional color options for spot beam coverage based on the operational status of the satellite.

• Default behavior is unchanged (all colors are the same)
• Additional options to change the color for certain operational statuses

You can set independent colors for these statuses:

• Fully Operational
• Partially Operations
• Non-Operational

The following statuses will always be the default color:

• Unknown
• standby
• spare
• extended

It wouldn't be too hard to extend the settings to the full list of statuses, but:

• this is all I needed (it's all my TLE Files support)
• It's a pain to add a bunch of new settings, so a design decision should be made about the best way to set it up. a few options
  • Just 'brute force' through all the color options for the full set of {map, polar} times {satellite, ground track, coverage)
  • Come up with a nested/OO approach to settings
  • Change the way settings are stored all together (ick)

Same comment as for pull request #132; however, in this case, there is also issue #8 to keep in mind.

I just tried this and it looks like resetting the colors to default does not apply to these new settings.
On one hand, I'm fine with getting this in although it would be nice to have options for some of the other statuses as well. On the other hand, I agree that the existing config system is a pain and should probably rewrite that first... Unfortunately, the same applies to most of the application, haha 😀
