Embed Interop Types settings for packages

[Jozef Izso]

NetOffice packages used the PowerShell script to configure the project file with correct EmbedInteropTypes setting. As we moved to the dotnet pack format of packages, these PowerShell scripts are no longer used.

We must update packages so NetOffice libraries are referenced using the <EmbedInteropTypes>False</EmbedInteropTypes> setting.

Adding the NetOfficeFw.Excel v1.9.1 package to a new .NET Framework console application project which used the packages.config file to manage NuGet packages will produce project which cannot be compiled:

// error CS1752: Interop type 'Core' cannot be embedded. Use the applicable interface instead.
NetOffice.Core.Default.Console.WriteLine("NetOffice bug #371");
// error CS1752: Interop type 'Application' cannot be embedded. Use the applicable interface instead.
var app = new NetOffice.ExcelApi.Application();

NuGet will add <EmbedInteropTypes>True</EmbedInteropTypes> setting by default:

<Reference Include="ExcelApi, Version=1.9.1.0, Culture=neutral, PublicKeyToken=297f57b43ae7c1de, processorArchitecture=MSIL">
  <HintPath>packages\NetOfficeFw.Excel.1.9.1\lib\net462\ExcelApi.dll</HintPath>
  <EmbedInteropTypes>True</EmbedInteropTypes>
</Reference>
<Reference Include="NetOffice, Version=1.9.1.0, Culture=neutral, PublicKeyToken=297f57b43ae7c1de, processorArchitecture=MSIL">
  <HintPath>packages\NetOfficeFw.Core.1.9.1\lib\net462\NetOffice.dll</HintPath>
  <EmbedInteropTypes>True</EmbedInteropTypes>
</Reference>

Developer must manually change the v1.9.1 package references to no embed interop types.
