* 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
