- added history parameters for chat lobbies
- added max storage time for items in chat history. Avoids filling up the history with chat from volatile peers.
- worked out the layout in config->ChatPage in a more compact design and added help
- set the max size of chat messages to 6000 bytes instead of 2000 which was a bit too low
- default max number of lobby messages saved in each lobby is 20. Avoids flooding for peers who havn't configured it yet.
