Save both replays and merge allied chat

[lladdy]

This might be a good way to represent what both bots put in allied chat.
Currently you only get the allied chat of the bot whose perspective the replay is from.

We could save both replays and merge the allied chat from the other so as to have both allied chats.
This means bots can safely dump their strategies into chat without being sniped and viewers can still later see each bot's strategy dump.
