Add pagination to Slow

[ai]

Right now having slow feeds with 100+ posts freeze browser when you open them.

So we need to add pagination. Requirements:

1. As with pagination in fast we need to keep the current page in URL.
2. Adding new posts should not change posts in pages. So it is better to use since rather than page in URL.
3. In contrast with pagination in fast user need to see how many pages are in the list.
4. Users need not only next page, but also the last page link, etc.
5. The small 1, 2, 3 links are not very useful. We need something better in terms of UX.

In terms of UX, does something like this make sense?

@pekac >/>> graphic language is not clear for most of the people.

I will ask my friends from design team for advice.

After internal discussion we decided for something like progressbar

[----+++---------] 400 posts
[Next page]

and you can click in the area of progress bar
