Made new log CVAR for overriding filters on error log types: zr_log_error_override. If this is on, errors are always logged, independent of flags and filters. Now all non-error logging can be completely disabled without complex flags or filtering.
Made new class attribute ("has_napalm", ClassGetHasNapalm) that specifies if the class have or can trhow napalm grenades. Implemented usage in napalm module.
Added team id validation in class attributes.
Improved formatting of log messages in cvars module.
Known issue: Commands in config for adding modules to log filter are executed too late. Otherwise the module filter works fine.
Fixed error getting default classes on early player connect (bots, source tv, etc.).
Fixed jump boost not resetting height velocity. Changed to add to velocity. Jump from boost platform still doesn't work because the velocity is set too early.
Added check for reserved class names when validating.
Updated class default attributes and jump limits.
