Hightlight My Planets – Add support for persisting chosen settings

[cristobal]

This PR adds support for persisting chosen settings to localStorage for situations such as :

1. When closing and opening the plugin manually.
2. One has to refresh the game site due to memory leak and/or other factors that makes game not playable anymore and a hard refresh is needed.
3. The browser quit and/or restart of the machine

In theory this is an improvement to the plugin and a nice thing to have, but for security reasons we should not work with localstorage.

If you look at the readme of this repo under Contribution Guidelines it says:

No use of localstorage, overriding internal rpc timers/settings (df.contractsAPI.contractCaller), interaction with or depending on other plugins

I made an issue on how we can maybe use indexedDB instead
#174
but I dont know what the devs currently think about it

Yeah i talked with @phated about this on Discord, where he has some other ideas to try out when it comes to plugins.

I can just close this PR and wait for changes to the plugin system and sumbit a new PR when the time is right 😊👍
