CSharp client: optionally build .csproj file

[jhancock93]

Adds 2 parameters to csharp build options. One to control whether a project file is generated and another which can specify the Project Guid for the csproj.

Addresses open issue #1883.

@jhancock93 thanks for the PR. It failed the generator test:

I did a test and believe the default should be false, right?

[jhancock93]

Correct, the default should be false. Initially I had it default to true but forgot to change the description. I can fix that.

After setting optionalProjectFile=true when generating the C# petstore sample, I opened samples/client/petstore/csharp/SwaggerClientTest/Lib/SwaggerClient/src/main/csharp/IO/Swagger/IO.Swagger.Client.csproj but got the following error:

I'm using Xamarin Studio 5.10 and Mono 4.2.1.

Did you get similar error when opening the csproj file?

[jhancock93]

No, I don't get the error you're seeing with the project file. I can open the .csproj file in VisualStudio with no errors. But I suppose we probably need a somewhat different template in Xamarin. I don't have Xamarin Studio myself, but I suspect the targets file or the TargetFrameworkVersion would be different with Xamarin.

[wing328]

I've changed the following

    <TargetFrameworkVersion>v4.5.2</TargetFrameworkVersion>

to

    <TargetFrameworkVersion>v4.5</TargetFrameworkVersion>

and that works for me in Xamarin Studio

Would that also work for you in Visual Studio? If yes, please update to use v4.5 instead.

[jhancock93]

4.5 works for me. I've updated the branch with the code change to 4.5 and the correction on the default value in the option description.
