Encourage users to donate more

[Nutomic]

Lemmy is entirely reliant on donations to function, yet the current amount of donations is barely enough to fund development, and some instances also dont receive enough funding.

To improve this I suggest to display donation links more prominently. Namely on the homepage, below the sidebar text we can show the following:

• Donation info for Lemmy development
• Donation info local instance
• Donation info for current frontend/app

It could also be shown above the sidebar and collapsed by default. For the local instance, there needs to be a new config option with markdown text for the donation info. The backend returns this together with donation info for Lemmy development. Frontends and apps can add their own donation info as well.

Additionally, when viewing a community we could show this:

• Donation info for Lemmy development
• Donation info for instance where community is hosted
• Donation info for current frontend/app

In this case it would be necessary to federate the donation info.
