Implement assembly resolution for FsiReferenceCommand

[dungpa]

It turns out that we can use assembly resolution from F# Project System to ensure that assembly ordering is resolved correctly by default. We still keep the revised ordering if users decide to change it.

It isn't obvious to me until this conversation fsprojects/Paket#677.

@vasily-kirichenko Could you take a look?

I'll take a look later today. The idea is great.

1. Generate from scratch

// Warning: generated file; your changes could be lost when a new file is generated.
#I __SOURCE_DIRECTORY__
#r @"..\..\packages\ExtCore\lib\net45\ExtCore.dll"
#r @"..\..\packages\FSharpx.Core\lib\40\FSharpx.Core.dll"
#r @"..\..\packages\Hopac\lib\net45\Hopac.Core.dll"
#r @"..\..\packages\Hopac\lib\net45\Hopac.dll"
#r @"..\..\packages\Hopac.Extras\lib\net45\Hopac.Extras.dll"
#r @"..\..\packages\Hopac\lib\net45\Hopac.Platform.dll"
#r @"..\..\Libs\Microsoft.ConcurrencyVisualizer.Markers.dll"
#r @"System.Core.dll"
#r @"System.dll"
#r @"System.Numerics.dll"
#r @"System.Xml.Linq.dll"

1. Add a reference at end (or any other place)

// Warning: generated file; your changes could be lost when a new file is generated.
#I __SOURCE_DIRECTORY__
#r @"..\..\packages\ExtCore\lib\net45\ExtCore.dll"
#r @"..\..\packages\FSharpx.Core\lib\40\FSharpx.Core.dll"
#r @"..\..\packages\Hopac\lib\net45\Hopac.Core.dll"
#r @"..\..\packages\Hopac\lib\net45\Hopac.dll"
#r @"..\..\packages\Hopac.Extras\lib\net45\Hopac.Extras.dll"
#r @"..\..\packages\Hopac\lib\net45\Hopac.Platform.dll"
#r @"..\..\Libs\Microsoft.ConcurrencyVisualizer.Markers.dll"
#r @"System.Core.dll"
#r @"System.dll"
#r @"System.Numerics.dll"
#r @"System.Xml.Linq.dll"
#r "System.Runtime"

1. Compile the project
2. The added reference disappeared.

It is the expected behaviour (that isn't affected by this change). We don't care about new entries; they will be removed if they don't appear in the list of references.
