Add setting to manually select dark/light mode

Add setting to manually select dark/light mode as seen in SecUSo/privacy-friendly-qr-scanner#174

@udenr can you please help me implement this? I know you implemented this feature in another SecUSo app, as mentioned in the OP of this Issue. I'm having trouble figuring out how to rewrite SettingsActivity.java, but have added code from your commit here jahway603@5594b0f. Any help would be appreciated.

This app does not even support dark mode yet. Maybe that's the problem why it's not working for you. You first need to change the theme to one that supports dark mode and then adjust the colors. This should work similar to this commit. Then it should already follow the system settings. You might need to adjust some additional resources or code, that everything uses the new Theme as seen in this commit. I hope this helps.

Still the same issue. I installed some of your programms, but as there is no dark/amoled-black/night-mode availlable, I'm not very often using your tools. They're just to bright and hurt my eyes.

I've installed the following of your tools:
Version 2.3.0
org.secuso.privacyfriendlyfinancemanager

Version 1.1.1
org.secuso.privacyfriendlyruler

Version 1.1.1
org.secuso.privacyfriendlytapemeasure

Version 1.2.2
org.secuso.privacyfriendlybattleship

Version 1.3.2
org.secuso.privacyfriendlypaindiary

@DrDustwolf I agree that the apps without a dark theme are to bright and also hurt my eyes.

@jahway603 Can you create a pull request with your changes? Maybe I can take a look at it and fix it if there are only minor changes required.

Just created a PR with my changes.
