dnsapi omg.lol: fix info

Description "Based on the omg.lol API" is useless for users so removed.
The link to api moved to comment bellow.
Domains: omg.lol is unnecessary because the DNS provider name is anyway omg.lol.
Site: changed to point to the https://omg.lol site.
Issues: put a link to the support issue.

Remove the useless "Please Read this guide first" comment.
Fix typos.
