Add other keywords for similar emojis

[dantehemerson]

I noticed that some emojis can be represented with different keywords, so I added the different keywords for some emojis.

• for :poop: :poop: :hankey: :hankey: :shit: :shit:

• for :thumbsup: :thumbsup: :+1: :-1:

• for :thumbsdown: :thumbsdown: :-1: :-1:

I also added a new emoji, which solves the fix #33 :card_file_box: :card_file_box
