Multiple Wave instances created using the API share the same Log instance

[jamaa]

Multiple Wave instances created using the API share the same Log instance, which is no good. This also causes the below exception when trying to open the LogWindow in both instances.

System.InvalidOperationException
  HResult=0x80131509
  Message=Ungültiger threadübergreifender Vorgang: Der Zugriff auf das Steuerelement LogWindow erfolgte von einem anderen Thread als dem Thread, für den es erstellt wurde.
  Source=System.Windows.Forms
  StackTrace:
   at System.Windows.Forms.Control.get_Handle()

   at System.Windows.Forms.Control.Show()
   at BlueM.Wave.Log.ShowLogWindow() in H:\DEV\BLUEM\CODE\BlueM.Opt\BlueM.Wave\Log.vb:line 120

  This exception was originally thrown at this call stack:
    [External Code]
    BlueM.Wave.Log.ShowLogWindow() in Log.vb

Individual instances each need to have their own Log instance.
