Added VB.NET NSpec Specs project to solution with one passing test
Add VB versions of remaining two Describe_Example tests from describe_Example.cs to show VB tests are valid.
Added TheExampleCount to when_running_specs.cs and two tests in describe_example.cs to show its behavior.
Added tests to Describe_Example.vb calling TheExampleCount, where the one covering a class with anonymous lambdas is failing demonstrating #69.
Fix #69 by filtering out methods containing '<' or '$' as anonymous lambdas are named like 'Void_Lambda$__1()' in VB.NET.
Added running of NSpecSpecsVB to Rakefile.
