Add configurable MaxChatMessageLength to override default limits for older versions

Browse source 
Adds a MaxChatMessageLength config option under [Main.Advanced] that allows
users to override the protocol-defined maximum chat message length. Default is
0 (auto: 100 for MC 1.10 and below, 256 for MC 1.11+). Some servers like
Hypixel support longer messages on older versions, so this lets users set a
custom limit (e.g. 256 on 1.8.9). Includes a warning about potential kicks
if set incorrectly.

Closes #2947
