NuGet.Build.Packaging was bumped[1] to fix the build in mono-addins.
So, we pick up that change from mono-addins. And update
NuGet.Build.Packaging to v0.2.0 to be in sync.

The IsDotNetProjectOnly condition is not correct because it is using
the project selected in the solution pad to check the type, and
that may not be the project for which the options dialog is being
opened. The right solution is to use the ItemType condition to
check the type.
This commit also includes a bump of Mono.Addins that fixes a bug
in Not conditions.

crashing)
