Add start/console commands to help
on_message => on_direct_message in README
Fix reply options

Whoever wrote Bot.reply forgot to pass on options it received for
replies!
Fix direct messages

Someone renamed on_message to on_direct_message in bot.rb, but forgot to
update it in the template.

It used to be on_message in the template, so for less confusion, I think
it's preferable to just rename on_direct_message back. :o
