PR3031 Enhance support for Windows 2008 server over remote desktop 

I will just repeat what I stated in Issue 3031:

I can run my monogame program on several windows 7 and XP, without any trouble.
When I try to run it on Windows 2008R2 Server accessed via remote desktop/spice (I have reproduced it on two virtual machines, one of them just installed and updated) it fails with exception:

Unhandled Exception: SharpDX.SharpDXException: HRESULT: [0x887A0004], Module: [Unknown], ApiCode: [Unknown/Unknown], Message: Unknown

According to http://msdn.microsoft.com/en-us/library/windows/desktop/bb509553%28v=vs.85%29.aspx
that exception means:
DXGI_ERROR_UNSUPPORTED 0x887A0004 The requested functionality is not supported by the device or the driver.

Debugging monogame, I have also found that on the 2008 machine I can´t create a GrapchicsDevice with DriverType.Hardware (Reference and Warp drivers are ok), or with any FeatureLevel (not even 9_1).

I want to be able to run the program on windows 2008 server boxes, which needs the following corrections:

- Let the program run, although GetSupportedFeatureLevel() fails.
- Let the programmer choose the driver type (not only Reference driver, as it is supported now, but Warp too, which is faster)
- Check for supported FeatureLevels before requesting them, and if they are not supported, do not request them to the SharpDX.Direct3D11.Device constructor

------------------------
By the way, the UseReferenceDevice that I replace with UseD3DDriverType, has not made its way to  stable yet.
Ok.
I have restored UseReferenceDevice in commit 19dcfd7.
It works as you suggest, updating driverType.
