Improvement isn't as good as the EMP one in normal cases, but for intentional lag bomb saves it is much better. Tested it and confirmed it worked just like before this commit. etrd_life0_count is hopefully valid, the accuracy may not be as good as in jacksonmj's fork
flood fill brush is hidden when deco tools are selected like this because it gets in the way. Renderer::vid is compared here so there could definitely be issues, but it works fine when used under normal conditions
I've left some of the less important items, like SearchView.cpp "'then' statement is equivalent to the 'else' statement", and RequestBroker::Request::~Request, because I don't feel like spending a few days entirely rewriting those files at the moment (which is what I'd end up doing if I started fixing minor problems and refactoring...)
GameSave::readOPS - not changed. At some point we may have to move to a larger type for element IDs (probably two or four bytes), but PT_NUM isn't likely to be raised to the maximum value of that type immediately, so this check will be needed then. There should be an elements[partsData[i]].Enabled check in there too, but it might be a bit difficult - I'm not sure how to access a Simulation object from GameSave::readOPS...
Notes on changes:
Graphics::textsize, Element_FRZW::Element_FRZW - typos
Button::Draw - the extra case was originally used to invert the icon (draw it in black instead of in white) when the button was clicked. However, the icon colour is now automatically set depending on the background colour. (Note similar conditions "if(Enabled) { if(isButtonDown || (isTogglable && toggle)) " near the start of the function - same logic but in a different place, setting icon colour indirectly).
Simulation::transform_save - unused redundant function, everything uses GameSave::Transform which does much the same thing.
PreviewView::NotifySaveChanged - should be height==YRES/2, it's checking whether the preview image is the correct size, and resizing it if it isn't.
Element_FWRK::update - no idea why that line was there, even though it was my commit that originally added it...
