Add a little bit more statistic info in the status bar

[WimYogya]

In the bottom right corner of the main window the statusbar shows the number of files in the window (let's say: 10.000).
If you do a search (let's say) Barbra Streisand, the number of 'hits' is shown, let's say: 500.
Then, if you SELECT a number of those files, only the number of selected files is shown, let's say 50.
In examples like these it would be nicer if you see (as in this example): selected 50 of 500 files, adding the 'of 500' remark.
Can be relevant information, for instance when you are preparing deletion of the duplicate tracks in an album.
If you have 46 files in the album, and selection says 'selected 23 of 46 files', it is an easy check that you are 'on track'.
Thanks.
