add check for empty block in fluid sigil placement, and waterlogging

[Phil-M-H]

1. Fixes Issue 1862
2. Added waterlogging to the water sigil

I edited the changelog as well since I saw some other PRs do that -- just let me know if you'd prefer I don't touch that.

To be clear, issue #1862 still exists in the latest versions (I accidentally broke an end portal frame on a server I was hosting because I right-clicked on the side of an eye of ender), I just dug up the issue so it could be closed out.

I've been adding to the changelog because its usually just me and thus everything is in order and github shouldnt be whining about there being mismatches. also theres the changelog.txt and the changelog book entry which should both be updated at the same time.

It would be easier for us if you removed the changelog entry and we'll add it ourselves once we merge it
