Fixed an issue when DNS resolving fails.

In the event of a failed DNS Resolving checking for new versions will
cause a huge delay, and in the end a timeout when loading the page.

- Check if DNS resolving failed, if that is the case, do not check for
  new versions
- Changed `fn get_github_api` to make use of structs
- Added a timeout of 10 seconds for the version check requests
- Moved the "Unknown" lables to the "Latest" lable
