Add followSystemTheme config option

[benterova]

• New command line option --followSystemTheme. Defaults to false.
• When following system theme, set Teams theme to the current light/dark setting after a small delay on startup. (2.5 seconds, if you attempt to do this too soon Teams freaks out and only updates the outer window with the new theme)
• Update Teams light/dark theme to match system theme when the system theme is changed.

@benterova thanks for your efforts ❤️ could you update the package.json with version number? I think, it would be 1.4.6

@benterova sorry, there was a merge in between. Can you sync your fork and update once again please? The version was changed to 1.4.6 already.

Updated again

@benterova it shows merge conflict. I guess you have to sync your fork and push again.

Thanks @benterova. I fixed the conflict and merged. Thanks again! I'm sure the community will be very happy about this new addition.
