Bug#506843: update-manager: changelogs should check APT config for proxy

[Gábor Németh]

Package: update-manager
Version: 0.68.debian-7
Severity: normal

This version of u-m does not check for proxy settings in apt.conf,
therefore changelogs do not appear when behind a firewall.

A solution is included since upstream version 0.93.1; please update from
that or consider adding a trivial patch like this:
