pixiv server update

[UjuiUjuMandan]

So now pixiv has updated their image server, it doesn't allow invalid HTTP Host header anymore. We should correctly build the URL, by inserting a domain instead of direct IP address.

This patch doesn't fail to Chinese censorship.

• For DNS, a DoH server was already used.
• There is no DPI targeting i.pximg.net as an HTTP Host but only it as an HTTPS SNI. The current HTTP_HEAD = "http://" is no problem.

Before this is fixed, an workaround is to set Pixiv proxy host to i.pximg.net in Advanced settings.

Have you noticed that you sometimes use antony@antonyhu,cin,au in commit? Every typo moves one key left.

I'll take a look at this when I get time over the next week

Good point about the typos, I didn't notice it until now! I'll fix it in Sublime Merge right away
