Fixed displaying players in Highscores. Some players in Top Players widget will be hidden when theirs group_id is higher than specified in config("config.highscore.ignoreGroupId - Ignore group id higher than this (staff)"). Same in Highscore subpage. Also fixed undefined index `page` in Highscore. This resolves #43 issue.
Marketplaces improvements. Replaced @ operator(as Znote suggested) using assign-by-repherence. Fixed `invalid argument supplied for foreach` errors when `compare` in URL string was type of `String` or did not match any of the items from the list.
