[FAQ] Links updated

[Ben Bullock]

I've done a check for dead links etc. on www.sljfaq.org/afaq/. A few sites and articles (ijnvariably the links to Japanese-language sites) have disappeared, so I linked them to archive.org. Where a forum or online dictionary had disappeared, I just commented out the link. Other redirected sites are linked up appropriately. Fortunately about 95% of the links were OK.

I've also removed kanjiclinic.com from

https://www.sljfaq.org/afaq/websites.html

The site was replaced by a domain squatting site.
