Check Github Trending

The idea is to know which trending repos I have already checked, to avoid having to check them again in the future.

The list of reviewed trending repos is kept in a lightweight text-only database, that consists of the reviewed repos with a timestamp of the last revision date. If the revision date is greater than N months, the repo is marked once more for review. New repos and stale repos are opened in the browser.

1. Run download_trending_repos.sh, that will fetch the list of trending repos and write them to currently_trending_repos.txt, sorted by stars. matter if there are other tabs).
2. Run check_github_trending.sh.

• revert changes if the process is killed before completion
• let me mark repos as not interesting, to never prompt about them again
