Added skin tone option

[Glennmen]

• Default no skin tone (keep same behaviour)
• Added environment variable to change skin tone (0, 1, 2 ,3, 4)
• Added shift modifier to copy emoji without skin tone

fixes #31

This was my first time working on an Alfred workflow 😅 but it was a lot of fun. I am open for feedback.

First credits to https://github.com/muan/mojibar for inspiration how to add skin tone to an emoji.
Also there are a lot of emoji that should support skin tone but the emojilib is a little out of date it seems. Hopefully it will get updated soon.
I also didn't know if I should add skin tone to Copy code :+1:, I couldn't find any information if there is any spec for this or if every app implements this in their own format.

For now I used an environment variable skin_tone, but a good next improvement would be adding a new Alfred command to change skin tone.

What happens if a skin tone doesn't exist? Does it fall back to the neutral tone?

[Glennmen]

@jsumners Do you mean when you set a skin tone value higher than 4? It will fallback to the neutral tone.

Also there are a lot of emoji that should support skin tone but the emojilib is a little out of date it seems.

So if a user has set that they prefer some alternative tone, and the emoji they are choosing doesn't support it, what happens? Can you paste a gif of such a search?

[Glennmen]

@jsumners That is what this line is for:

https://github.com/Glennmen/alfred-emoji/blob/2973921b00747ef706d16c838becd47811bb3db0/lib/genicons.js#L18

It will check if the emoji has skin tone support.
I am also writing some extra tests right now, will commit it in a few minutes and see if I can make a video.

@jsumners Here is the gif, I hope this answers your question 😄

Currently emojilib is very outdated it seems, that is why those smiles currently don't have a skin tone.

Thank you for the gif; it answers my question clearly.

I know. They are working on a restructuring on the library to follow Unicode releases. It's a difficult problem to tackle. I used up a whole day on it a while back and got basically nowhere (https://twitter.com/jsumners79/status/1211105577188970497). I may get back to it soon 🤷‍♂ .

[Glennmen]

@jsumners If emojilib does the major update, it seems it will have a lot of breaking changes, feel free to tag me and if I have the time I will be happy to implement them. I went through the emojilib PR and unicode-emoji-json yesterday and it seems doable 🤔

I applied your suggested changed 🎉

[Glennmen]

There seems to be an error in one of the travis builds that are not related to the changes 🤔

[Glennmen]

@jsumners Anything you want me to change? Just let me know 😄

[jsumners]

No. I just need to get around to dealing with it. I want to add in some GitHub Actions (maybe).
