Fix GH-41 -- Commands with newlines in args not recognized

Before this commit, if you try to send a command with a newline in the
args, botogram fails to recognize the message as a command. This commit
fixes this, and also considers `\n` and `\t` as spaces while splitting
the message in search for arguments.
