[Feature request] New list variables placeholders

[Limeen]

As for normal variables placeholders there is :
%servervariables_value_otherplayer_<player>:<variable>% and %servervariables_display_otherplayer_<player>:<variable>%

I think it could be really useful to have those for list variables placeholders :

• %servervariables_list_contains_otherplayer_<player>_<variable>:<value>%
• %servervariables_list_values_otherplayer_<player>:<variable>%
• %servervariables_list_value_otherplayer_<player>:<index>_<variable>%
