slack integration

we imagine from within a project channel starting a vote like this:

> @async_bot start vote on http://ticket/id

then bot would respond with vote instructions in channel

> vote on http://ticket/id "title", please DM 1(simple), 2 (medium), 3(hard) to me at @async_bot - please discuss here in channel or in ticket as preferred

then individuals DM bot and bot updates channel with names of voters, revealing the vote values when we reach a threshold of, say 3 votes

would love to have vote take on icon of person who started the vote
