Water/whiteout colouring the GUI bug fix

EDIT: To clarify the bug:

When you go underwater the gui controls get coloured blue by the water effects. The code below changes the order of the rendering so that the controls are rendered after the water and whiteout effects.

Although this is a really trivial change, there doesn't seem to be a snipit or resource covering how to fix this bug, so I decided to post it here under the bugs.

Firstly, in GuiTSCtrl::onRender, find:

renderChildControls(offset, updateRect);

and comment it out.

// renderChildControls(offset, updateRect); removed to prevent gui colouring - MJC

Then in GameTSCtrl.cc, in GameTSCtrl::onRender, find:

if(GameProcessCameraQuery(&camq))  
      GameRenderFilters(camq);

and insert the following immediately after it:

if(!skipRender) // added by MJC to not render controls coloured by effects
	  Parent::renderChildControls(offset, updateRect);

Then in EditTSCtrl.cc, in EditTSCtrl::onRender, find:

Parent::onRender(offset, updateRect);

and insert the following immediately after it:

Parent::renderChildControls(offset, updateRect); // MJC - render children separately

And that's all there is to it.
