Add icon pack support for Weather component

[driedpampas]

I got a cute idea and here is the result. I also forked and prepared an icon pack (material-weather-icons) already.

And I might have added myself to the Romanian translators, but it feels like I'm being greedy, so if needed it'll go poof

changes:

• add iconpack as a type and introduce it as a value
• modify settings.html for iconpack section and options
• make the current icons the default pack
• add a new string to translations.json for en and ro
• minor change: ignore bun.lockb in .gitignore

It occurred to me that we could iterate over folders and create a dynamic pack list which wouldn't require manually messing with the html but idk how to feel about it. (basically more feedback needed)

Also an unrelated question: Is the dev branch for the next major version or a staging spot for the next release's features (major or minor)

Also also, I saw the issue about the downloading backgrounds and i kinda wanna try my hand at it (mostly because it annoys me - i download way too many backgrounds from unsplash)

Nice @driedpampas ! This is a very interesting idea 🤔

We are super strict about the features that we add, which means I cannot accept your PR as it is. There are a few things to note:

• Users cannot simply add files to Bonjourr because of permissions, so the feature would need to load the icons from storage or a distant URL instead of a simple path.
• Users could add for each weather a URL (https://developer.accuweather.com/sites/default/files/01-s.png for example), or a local file (like the local background feature)
• That means a lot more options in the settings menu, which might not be easy to implement.

This feature is a lot trickier than it seems. It might be easier to simply add a CSS class for different weather icons, and instruct users on how to add a different background-image for each icons using the custom CSS feature.

Having said all that, you can make a different PR on master to add your translation credits to the README (you deserve it), and the bun.lockb why not.

dev is also a staging branch, this is where things are sure to be added and should be working for the next version. If you want to try adding the download icon, you can create a different branch and a different PR. There is no guarantee that we will accept your changes however !

You can also try that on a different branch if you want. If you manage to make it work, this will be included in the next major update !

Todo:

• Add a class or dataset for each icon
• Load the icon using background-image
• Custom CSS should override the default background-image
• Be careful about potential layout shifts !

Thanks for the feedback and the todo list and I will make a separate pr for the tl credits and the .gitignore. I was expecting some of it, so I'll see if i can whip up something more robust but as you noted it will be quite tricky.
