Added 4 new all-handy script functions; special thanks to KeyWorld!
* getargcount() -- to be used inside functions/callsub labels, returns quantity of arguments provided * is_function(<function name>) -- checks weather a "user" function exists, returning 1 if function is found and 0 otherwise. * freeloop(<toggle>) -- lets you to enable/disable (1 or 0) the loop infinity protection for that specific npc instance, allowing your script to loop as much as it may need. * get_revision() -- retrieves the current svn revision git-svn-id: https://rathena.svn.sourceforge.net/svnroot/rathena/trunk@15340 54d463be-8e91-2dee-dedb-b68131a5f0ec
