a simplistic slack bot

bot, _ := slacker.SlackBotInit("A1110001114", "xoxb-1337133713375-1337133713371-13371337133713371337RFI", true)
bot.SendCriticalMessage("", "scan failed")
'''
channelID: A1110001114
token: "xoxb-1337133713375-1337133713371-13371337133713371337RFI"
can work with user & bot tokens: bots must be able to:
