Add 2014/vik/try.sh, update bugs.md, fix clobber

The bugs.md has more details on the bug I discovered when working on
2020/ferguson2. Even the usage in the try section (now in try.sh)
resulted in files that cannot be translated to English right.

The make clobber rule now removes *.raw instead of specific raw files.
This is important for clean up prior to updating the manifest.

Updated .gitignore.
