- fixed malloc and used g_new or g_malloc in all places
- i double bumped the version accidentally - undo formatting of not touched code (the other is that different, that it wouldn't be recognizeable anyway) - removed the limit option completely, also resulting in removing the /checksum command - use g_strdup instead of some manual stuff + strcpy
