SoftwareCenterApp autocompletetion has many entries with the same name

[Schwarzburg]

Steps to reproduce (rev.89):

1) Open the SoftwareCenterApp tab.
2) Wait till autocompletion loading has finished
3) Type e.g. xpuzzles (see screenshot)

The actual numbers of the entries vary, some are there only once (e.g. osmo).

[David Planella (dpm)]

I think the first thing might be to find out why the Software Centre database returns multiple entries for some apps, but in any case I believe we can easily solve it in the code by using a python set to contain the list of apps, rather than a list (I'm talking from memory here, I'd need to check on the actual code).

[Schwarzburg (stefan-schwarzburg)]

I think I understand better:

printing the names and packages, it looks like this:

xbarrel xpuzzles
xcubes xpuzzles
xdino xpuzzles
xhexagons xpuzzles
xmball xpuzzles
xmlink xpuzzles
xoct xpuzzles
xpanex xpuzzles
xpyraminx xpuzzles
xrubik xpuzzles
xskewb xpuzzles
xtriangles xpuzzles

So the autocompletion shows the package in which a program is.

Two solutions:
1) actually show the app name
 - pro: the user can find the app
 - con: the user can not see the actual package name he is ablout to link to

2) only show the package:
 - con: the icons might differ a lot between the apps in a package, so chosing one app icon for the package might mislead the user

 - con: the label suggests that you can search an app (not only a package)
