New Options Dialog has a typo which is persistent into codebase

The Options dialog is a nice improvement.

Please note, however, the label for "Anisotropic Filtering:" is misspelled as "Ansiotropic". Normally, I fix these, and just go on my way, but this one is reflected throughout the code, at which point it may become impactful if allowed to persist.

Script side:

C:TorqueTorque 3D 2009 Pro 1.1 Beta 1My Projects...gamecoreartguioptionsDlg.gui(1117): text = "Ansiotropic Filtering:";
C:TorqueTorque 3D 2009 Pro 1.1 Beta 1My Projects...gamecoreartguioptionsDlg.gui(1165): internalName = "OptAnsiotropicPopup";
C:TorqueTorque 3D 2009 Pro 1.1 Beta 1My Projects...gamecorescriptsguioptionsDlg.cs(139): %ansioCtrl = %this-->OptAnsiotropicPopup;
C:TorqueTorque 3D 2009 Pro 1.1 Beta 1My Projects...gamecorescriptsguioptionsDlg.cs(346): %level = %this-->OptAnsiotropicPopup.getSelected();

Engine side (only turns up in these comments):

C:TorqueTorque 3D 2009 Pro 1.1 Beta 1EnginesourceterrainhlslterrFeatureHLSL.cpp(495): // not using tex2Dlod() or that i'm using ansiotropic
C:TorqueTorque 3D 2009 Pro 1.1 Beta 1EnginesourceterrainhlslterrFeatureHLSL.cpp(617): // not using tex2Dlod() or that i'm using ansiotropic

Please note consistent transposition of "s" and "i". The term is correctly spelled as "anisotropic".
