Better feed management

[shizunge]

I have created a pull request for a better feed management: #642

Here I am talking about the visible changes. Hopefully this helps the code review.

1. In the "feed" page:

• For each feed, shows three numbers (instead of two): unread count, read count and total count.
• For each feed, shows the publishing time of the lastest post.
  

2. In the "feed" page:

• Add "sort by" button (Solved [Feature Request] sort feeds by last update time #632):
  --- click to show the sort menu. click again to hide the sort menu.
  --- click each item in the sort menu to sort the feeds.
  --- click item again to sort in the reverse order.
  

3. introduce a new status of entries "marked"

• If you click an entry (go to a URL ending by "entry/<number>"), they entry will be in the read status.
• If you mark entries via "Mark this page as read" or "Mark all as read", they will be in the marked status.

4. In the history page:

• Add "show only read entries" and "show all entries" to show different lists of entries
  --- add a path "history/read"
• Also update "previous" and "next" link of entries to go to entries in the corresponding list
  --- If from "all entries", the link goes to "history/entry/<number>" for both read and marked entries
  --- If from "only read entries", the link goes to "history/read/entry/<number>", which includes only read entries.

split the big commit into 3 smaller commits.

The first two commits are
-- add latest post published time to the feed page.
-- add total count to the feed page.
-- add sort to the feed page.
They do not modify the database, only change the feed page UI.

OK strange question, is there a way to sort feeds by category on the feeds page? Right now my feeds are all out of order. I suppose the other question is, is there a way to sort categories into alphabetical order? My former reader does this and I really like it.

I am using 2.0.21. And my categories seems already sorted alphabetically.

It could be done, I think.
But Why not use the category page?

2nd question
What would you do if we could asaign multiple categories to a feed? How to sort the feeds with multiple categories? (Currently we cannot. But I think eventually we will support it.)
