[Defconapi] Extensive use of SendChatMessage 3

[Jakub Gemrot]

Hi Robin, my fault! I've totally missed DebugLog method - that's
strange as I did not have them inside my JBot.java,
but I've been changing this file a lot lately (adding JavaDocs mainly)
and probably I've deleted them from the file by accident.

I'm going to poke these DebugLog() methods soon - thanks for pointing
that out! I don't think you really have to investigate that
issue with SendChatMessage(), only if you find free time :-) ... out
of curiosity.

Cheers!
Jakub
