modules/qrpn: replace stderr with stdout; remove extraneous whitespace throughout

Browse Source 
PBot modules do not send the stderr stream to the channel. Instead, the output
is logged in <module-filename>-stderr, for private debugging purposes. PBot
expects output intended for channels to be on stdout.
