Client: Hide deleted posts

[Kamuso]

Mostly completed feature. Doesn't work on page load, because posts is empty, in hideBinned(). I don't know what to change to get around this.

Oh, closes #1026

You should not be adding the hidden class on your own. Insead better integrate with the existing post hiding logic.

Add the post to the hidden set here to hide on page load: https://github.com/bakape/meguca/blob/master/client/page/common.ts#L141
Add a check on model creation here to hide any new posts: https://github.com/bakape/meguca/blob/master/client/posts/model.ts#L51
To hide posts on fresh deletes: https://github.com/bakape/meguca/blob/master/client/posts/model.ts#L214
You will also need to loop over the post collection and hide all already deleted posts, when the option is toggled on in options/loop.ts.

Ask, if you have any questions. I can explain some more specific things about the higher level architecture, if they are unclear.

Okay. I kept them separate to easily unhide on toggle, but it's not like that was important.

This time I've tried to keep behaviour as similar to how recursive hiding currently works, in regards to unhiding, new post tab icons, and hidden post count.

Looks good.
