[gnome-flashback] Listing releases on the home page

[Michael DePaulo <mikedep333 gmail com>]

Hi,

I noticed that recent releases (3.16.0, 3.16.1) haven't been listed on
the home page.
https://wiki.gnome.org/Projects/GnomeFlashback

I volunteer to update it.

I believe I should write titles like "GNOME Flashback 3.16.1 released
on 2015-04-15" and provide download links to each package. (In
addition to a brief description or the release.)
