Building a Windows Store App project with "Unity C# Projects" option checked, results in projects are being created with the wrong Unity version in the conditional compilation symbols, for example:

<DefineConstants>...UNITY_4_0_0;UNITY_4_0;...</DefineConstants>

Repro steps:
1. Create an empty project and build a Windows Store App with the Unity C# Project checkbox ticked;
2. Examine the Conditional compilation symbols for Assembly-CSharp-metro-vs2013 and Assembly-CSharp-firstpass-metro-vs2013 projects in Unity project folder;
