UI Support for showing basic weapon info

Introduced a Weapon concept like Spells into the Model.
Introduced a WeaponViewModel that knows how to display it.
Made UI show Weapon info for a character.
Removes All Azure Mobile Services code

We will use hard coded data until most functionality is up and running.
Then we will add a new layer for azure bindings later.
Main Library is now a Portable Library

It targets Desktop (4.5), Windows Phone 8, and Windows Store.
DragonCommander now just references the main DLL instead of
double-compiling the code.
