Access quotes

[SteKoe]

The quotebot should implement reactions for the following things:

• /quote #<id> will return quote having id <id>.
• /quote <name> will return a quote made by <name> .
• /quote rnd|Math.random()|random will return a random quote.
• /quote search <term> will return a random quote containing term.

Messages to a user only can be send via 'response_type = ephemeral'. In ordner to send message to the channel use 'response_type = in_channel'.
