Add a tool to check 1-4-12 criterion (WCAG 2.1)

[PigeardSylvain]

Is it possible to add a tool to test 1-4-12 criterion from WCAG 2.1
Here is a quick bookmarklet example (need to be validate) :

javascript:s%20=%20document.createElement(%22style%22)%3Bs.setAttribute(%22type%22%2C%22text%2Fcss%22)%3Bt%3Ddocument.createTextNode(%22*%20%7Bline-height%3A%201.5!important%3B%20letter-spacing%3A.12em!important%3B%20word-spacing%3A%20.16em%20!important%3B%7D%20p%7Bmargin-bottom%3A%202em!important%3B%20%7D%22)%3Bs.appendChild(t)%3Bh%20%3D%20document.getElementsByTagName(%22head%22)%5B0%5D%3Bh.appendChild(s)%3Bvoid(0)%3B

Thanks

Commited the Text spacing code.

It works for me.

@ffoodd please:

• test and confirm that we're OK
• add localization strings (I can't remember where you add them, apologies — too long off the project I guess)
• change version if everything is OK for you
• document for future developments where localization strings must be added
• package
