Bug#817896: gnome-core: should depend on firefox-esr | firefox instead of iceweasel

[Ansgar Burchardt]

Package: gnome-core
Version: 1:3.14+3
Severity: normal

Now that firefox is in the archive, I believe gnome-core should depend on
  firefox-esr | firefox
instead of iceweasel.

As far as I understand, firefox-esr will go in stable releases and
firefox will only be available in unstable, so firefox-esr should be
the preferred choice (and also the iceweasel transitional package
depends on firefox-esr).

Currently it is not possible to install only "firefox" and the gnome
meta packages as gnome-core pulls in firefox-esr (via iceweasel).
