Improve sorting of session playlists in History feature

[jus]

As dates increase in value as time goes on, the current session playlist sorting place your dates in oldest to newest order. This makes it quite hard to read, especially if the number of entries grow over the month.

I propose to switch to a ascending, from newest to oldest, sorting order with the following folder structure:

Year
  |
  Month
    |
    Date

+1, this would be better

I was going to suggest an option to auto-merge old history - something like any sessions older than a couple of days get merged by day, older than a month get merged by month, older than a year get merged by year, but this is a better suggestion.

Could we have it so that if you select the year, you get a merged version of all sub-histories?

Also, could we have it so that the more recent histories are at the top (reverse sort), and the most recent history is auto-expanded?
