Title:
  software-center ignores Replaces directive in case of Conflict

Status in software-center package in Ubuntu:
  Invalid

Bug description:
  I have encountered this problem with the CrossOver Office
  (http://www.codeweavers.com/products/) packages. They come in multiple
  flavors, but only one can be installed at a given time. The more
  capable flavors use the 'Replaces' directive to smoothly 'upgrade' the
  less capable ones. This works fine with dpkg, but software-center
  instead gives me an error as if the Replaces directive was not there
  (this directive is described in section 7.6.2 of the Debian Policy
  Manual).

  I have reproduced the situation with dummy packages so you have all the details. You can get them there:
   * source (1.4KB)
     http://fgouget.free.fr/tmp/gdebi/foo-packages.tar.gz
   * basic package (1.2KB)
     http://fgouget.free.fr/tmp/gdebi/foo_1.0.0-1_i386.deb
   * sophisticated package (1.2KB)
     http://fgouget.free.fr/tmp/gdebi/foo-pro_1.0.0-1_i386.deb

  Here is how to reproduce the problem:
   * Run:  software-center foo_1.0.0-1_i386.deb
   * Install the 'foo' package.  This is the package to be replaced by the more 'sophisticated' version.
   * Then run software-centeri foo-pro_1.0.0-1_i386.deb
   * You get the following message:
      > Breaks existing package 'foo' that conflict: 'foo-highlander'. But the
      > '/home/weaver/foo-pro_1.0.0-1_i386.deb' provides it via: 'foo-highlander'
   * The 'Install' button is enabled which is good, but when clicking on it disables the button and nothing seems to happen.
   * Indeed running 'dpkg -l foo-pro' shows the package has not been installed.

  So software-center does not want or fails to replace the foo package
  with foo-pro. I think it should maybe warn the user but still allow
  him to proceed. With dpkg there is no issue:

  $ sudo dpkg -i foo-pro_1.0.0-1_i386.deb 
  Selecting previously deselected package foo-pro.
  dpkg: considering removing foo in favour of foo-pro ...
  dpkg: yes, will remove foo in favour of foo-pro.
  (Reading database ... 127365 files and directories currently installed.)
  Unpacking foo-pro (from foo-pro_1.0.0-1_i386.deb) ...
  Setting up foo-pro (1.0.0-1) ...

  
  As a side not, the same issue plagued gdebi a long time ago and now plagues it again. See bug #146398.
