Fix#18 Leashing, leading, rubberbanding issues with spawns resolved
Issue #17 Work in Progress, size mod stat support in the works, setting temporary_scale in info struct seems to modify size, the pos_size values in the position struct are not for KoS and older clients.
AddSpellBonus was translating values from float to sint32 early, now we take bonus values into player add bonus so that float values will be honored, as well as sint32. This applies to uncontested parry, block, dodge, riposte and the size mod.
Rule support for R_Combat, MaxChaseDistance to restrict by server or zone the max chase distance instead of hardcoded 80.0.
Additionally GetInfoStruct float max_chase_distance added.
info struct takes precident when set greater than 0.0 for the max chase distance, otherwise we check the rule being greater than 0.0, otherwise we use the default 80 in the hardcode define
