Merging Radical.Windows.Presentation.Puzzle into Radical.Windows.Presentation

[mauroservienti]

Related to #6 what about merging the "Radical.Windows.Presentation.Puzzle" projects for Universal Apps into the "Radical.Windows.Presentation", in the end we are shipping the PuzzleContainer in any case and adding to the Radical.Windows.Presentation project 5 more classes should not be a problem at all compared to one less dependency to download from Nuget.

@enosrecanati @micdenny comments?

I think is a good idea, it's a kind of custom tiny IoC container, and should be hided, if someone want it to use in its project, it could simply copy the 5 classes instead of having a nuget package, I saw other projects do this.
