Pass the build's versions to the examples MSBuild call (#352)

Four example solutions include the src/Spring projects directly - Northwind
and the Quartz example are built by CompileExamples, SpringAir and
WebQuickStart are skipped - so MSBuild's Rebuild recompiles Spring.Core and
friends straight back into build/$(Configuration)/.

That call passed no version properties, so the rebuild stamped the SDK default
1.0.0.0 over what CompileSolution had produced. While every assembly was
1.0.0.0 this was invisible. Now that CompileSolution sets real versions it is
a hard failure: the clobbered Spring.Core is 1.0.0.0 while the copies already
distributed into the other projects' output folders are 3.1.0.0, and the next
example to reference two Spring assemblies dies with

  error CS1705: Assembly 'Spring.Messaging' ... uses 'Spring.Core,
  Version=3.1.0.0' which has a higher version than referenced assembly
  'Spring.Core' with identity 'Spring.Core, Version=1.0.0.0'

Apply the same versions to the MSBuild invocation. MSBuildSettings has no
VersionPrefix/VersionSuffix setter, so those two go through SetProperty.

Reproduced and verified locally with dotnet build on the Quartz example
solution, which takes the same path: building it without version arguments
takes build/Release/Spring.Core/net462/Spring.Core.dll from 3.1.0.0 to
1.0.0.0, and building it with them leaves it at 3.1.0.0.
