Addresses #374

After this change, what will happen if the template is used in a project that has a reference to the 2.0 release of Microsoft.CodeAnalysis?

I was assuming that templates intelligently install versions of nuget packages. But, it's not appearing to be a correct assumption. Can you confirm?

It's hard to tell from the documentation how this would behave. I'm not sure I'd be comfortable having the template force package upgrades, but at the same time I never use the templates myself so I'm not sure it matters.

@peteraritchie this looks good. Could you also add these nuget dependencies for the other item templates?

I'm still uncomfortable with having the item templates changing package references.

Can you explain your objection? Other item templates do this
