With the addition of this change, a lone `mach busted file` will throw an error (since this should only ever be used by actual humans, and not in automation or anything, the backwards-compatibility breakage isn't a huge deal). Now it's expected to pass in `mach busted file $COMMAND`, where $COMMAND is the mach command that you were running when the error occurred, and we'll figure out which bugzilla component to file the bug against for you instead of directing it to `Firefox Build System :: General` regardless of whether the issue has *anything* to do with the build system. We preserve `mach busted file general` as a backup command that doesn't do any of this heavy logic.
