PDA Chat Improvements

[Geevies]

• Made a bunch of improvements to the PDA chat program. Clicking on someone or a channel's name will now immediately open the chat. Text inputs will now not input unless you press enter.
• PDA chat messages will now have spaces between them, unless it's the same person sending multiple messages in a row.
• Updating a PDA chat channel's password will now output that it changed into the chat.
