* irc: Improve the parsing

Recognize commands case insensitive: the RFCs are not very concise about

this and I don't know about clients sending commands in lower case but

just in case and it won't hurt

Line terminator: according RFCs should be \r\n but some clients only

send \n, I was confused about this but the parser must be robust and

now any combination of \r and \n is recognized

-PREFIX = r'(:[^ ]+ +|)'

+PREFIX = r'(?ai)(:[^ ]+ +|)'

- message = message.decode()

+ message = message.decode().replace('\r','\n')
