[Feature request] Sync theme (light/dark) to system theme

[pmmontanari]

Since Ampcast already divides themes into Light/Dark, I was thinking that it would be interesting to be able to sync them based on the system theme, or for example based on time (probably easier to implement)

I just changed the app so that it remembers your recent light/dark theme selection. That should make switching between light/dark a bit easier.

I will probably add (optional) synchronisation at some stage. But it won't be any time soon.
