* Some NPC event related cleaning.

- Made event label deprecation message a warning rather than an error, as the scripts still work regardless of whether '::On' is used or not (since r6592).
- Introduced constant EVENT_NAME_LENGTH (51) for all event name struct fields to eliminate size inconsistency across all objects (was 50 and 51).
- Fixed event names, that are considered special attributes, were not wiped when the value was 0 (since r5707).

+	* Some NPC event related cleaning. [Ai4rei]
+	- Made event label deprecation message a warning rather than an error, as the scripts still work regardless of whether '::On' is used or not (since r6592).
+	- Introduced constant EVENT_NAME_LENGTH (51) for all event name struct fields to eliminate size inconsistency across all objects (was 50 and 51).
+	- Fixed event names, that are considered special attributes, were not wiped when the value was 0 (since r5707).
 	* Removed impossible condition in mob_parse_dataset as spawn_data::eventname was/is the same size as mob_data::npc_event (since r5707). [Ai4rei]
 	* Fixed map-server printing deprecation message, when monster event label was used as transport for special attributes (small/large monsters etc.) in script command 'monster' and related commands (bugreport:1274, since r6592, related r5707). [Ai4rei]
