Improve outdated version check

[Toffikk]

This pull request improves the outdated build check by querying the api if an update is actually available

When the server finishes loading we query the api asynchronously and return the build info (for example 1 build behind, with 5 builds and more behind throwing errors instead of warns, latest and corresponding alternatives to each when there is a newer mc version available on the downloads page than the one you have downloaded)

Would love some feedback on this

check comments for screenshot examples of the new output
