"Family" activity is in testing phase

[Rudra Nil Basu]

Hi,

  The "Family" activity is aimed at helping children understand how they are
related to their relatives. It was started in the branch "GSoC-Family"
(https://cgit.kde.org/gcompris.git/log/?h=GSoC-family).

During the second coding phase of GSoC, I made the following improvements:
* Improved the layout of the family activity to a grid based layout
   (Blog:

* Adding a new activity called "Family find relatives", which is an
   extension of the Family activity, where given a relation, we have to
   determine a pair which correctly denotes the pair

   (Blog:

  The activity is currently in it's testing phase, so any form of review in
the form of bugs, feature requests or just thoughts on the implementation
of the activity will be very helpful.
