Logbot for makerlog

it is a Makerlog client for iOS and macOS

fixed a lot of background state changes but there are still some state changes that I can’t fix. SwiftUI isn’t optimised for that :/

fixed a lot of network problems logbot should not longer send unnessery duplicate requests

reduced log feed refresh this should solve some navigation bugs and optimise the refresh performance

Markdown is back + updated placeholder to ImagePlaceholder (swiftUI likes it more) + updated discussions with Markdown again (now with a version without force unwarp !)
