Caps Lock not working with GuiTextEditCtrl [With Fix]

I know no more builds are getting cut for TBG, but I feel there may still be some merit in posting bug fixes for those of us still using it. I noticed this morning when doing some testing that Caps lock wasn't being respected by my GUITextEditCtrl's. I found a fix for this on the T3D forums and ported it into T2D.

In guicontrolsguiTextEditCtrl.cc

Starting around line 930 (It may be off a little from the core because I also added call backs for OnKeyDown):

Old:

if ( mFont->isValidChar( event.ascii ) )
   {
   
	   // Get the character ready to add to a UTF8 string.
      UTF16 convertedChar[2] = { event.ascii + modifier, 0 };

      //see if it's a number field
      if ( mProfile->mNumbersOnly )
      {
         if (event.ascii == '-')
         {

New:

if ( mFont->isValidChar( event.ascii ) )
   {
 
// hack to handle Caps lock, because OMG it doesn't work...

   bool caps = GetKeyState(20);
   int modifier = 0;
   if( caps && event.ascii>=97 && event.ascii<=122) { // If capslock on and character lowercase   
       modifier-=32; // Make lower case character upper case  
   } else if(caps && event.ascii>=65 && event.ascii<=90 && (event.modifier & SI_SHIFT)) { // If capslock on, character uppercase, and shift down  
       modifier=32; // Make upper case character lower case  
   }    
   //End added code
		   
	   // Get the character ready to add to a UTF8 string.
      UTF16 convertedChar[2] = { event.ascii + modifier, 0 };

      //see if it's a number field
      if ( mProfile->mNumbersOnly )
      {
         if (event.ascii == '-')
         {

Oh, I also added windows.h as an include. It was recommended on the post I borrowed most of this fix from ( http://www.garagegames.com/community/forums/viewthread/130515 ).
