Show list of unimplemented achievements and leaderboards #8
Description
While rewriting Gran Turismo 4 set to cruncheevos, I couldn't easily figure which achievements were not implemented because there were over 600 of them and only few were left missing. Had to manually visit the website and compose a list of all achievements, then diff it against achievements that were actually implemented with the script.
Would be nice to implement a CLI command that will show a list of unimplemented achievements and leaderboards.
