* Add clang-format * Multiple privatization changes "Participation handshake" this refers to the moment that the user's client sends the `askchaa` packet. * Server::m_clients is now private. Get a copy with Server::getClients() * Server::m_player_count is now private. Get a copy with Server::getPlayerCount() (Additional logic was added to handle the player count.) * AOClient::m_joined is now private. Get a copy with AOClient::hasJoined() * Added signal AOClient::joined(); will be emitted when the client first complete the participation handshake. * Renamed Server::updatePlayerCount to Server::playerCountUpdated * Privatized Server * Made Server members private: m_characters, m_areas, m_area_names * Added Server methods: getCharacters(), getAreas(), getAreaById(f_area_id), getAreaByName(f_area_name), getAreaNames(), getAreaName(f_area_id), getMusicList * Added Server helper methods: getCharacterCount(), getAreaCount() - This reduce code repetition of the following example: server->getCharacters().length(), server->getAreas().size() * Solved other merge conflicts * Added Server methods, various fixes * Added Server methods: getCharacterById(f_chr_id) * Various optimizations * More Server privatization changes * Made Server members private: db_manager, next_message_timer, can_send_ic_messages * Renamed Server members: * next_message_timer -> m_message_floodguard_timer * can_send_ic_message -> m_can_send_ic_message Added Server methods: getDatabaseManager, isMessageAllowed, startMessageFloodguard(f_duration) Made Server methods private: allowMessage * Added new fields to load for AreaData * Added fields: `area_message` (default: empty string) and `send_area_message_on_join` (default: false) * Added Server::clearAreaMessage * Cleaned up headers include (AOPacket excluded) * Removed most project file includes, moved to source file (cpp) * AOPacket was excluded because some methods modify the copy * Fix compile error when using MingW compiler * Appease clang by using proper or and putting it in parentheses * Remove extra semicolon
