VC120 files

Visual Studio 2013 eats all other visual studio versions, i think we should support it.

```
<stfx>do you let it autogenerate when opening VC11?
<stfx>with VS13?
<DrSchmid>No
<DrSchmid>I copy all dirs and that stuffs
<DrSchmid>Rename to VC120
<DrSchmid>open all files in notepad++ and replace 110 with 120
<DrSchmid>There's no real difference in VC12 and 13 other then "version number"
```
