Add all-time chart feature

Here is my proposed "best players of all time" chart.
Players are sorted by highest ranking achieved

Remaining stuff to do :

1) Fix annoying bug : When clicking on submenu Records / Protoss, Terran, Zerg or All the text of the submenu turn red (correct behavior), but it's not the case for History and Hof.

2) Add a filter for every country. For the moment it's only All | Non-koreans
