Allow Powershell to use EnvDTE.Globals properties as methods.

Added a VB.NET Globals class which implements multiple parameterised properties which are not supported in C#.
This allows Powershell to use properties on the Globals class as though they were methods:

$dte.Solution.Globals.VariableValue("MyValue") = "value"
Write-Host $dte.Solution.Globals.VariableValue("MyValue")
$dte.Solution.Globals.VariablePersists("MyValue") = $true
Write-Host $dte.Solution.Globals.VariablePersists("MyValue")
