Full Screen remember example for grickmin

[Nifflas]

grickmin asked me to explain how to create an application that remembers if it was set to full-screen or windowed when it last exited. Here's how I'd do it.

v3 is optimized to perform as few file accesses as possible.
v4 is optimized for less actions, and does not need a global value. It does however access the .ini file twice when you toggle between windowed and full-screen. It's no big deal, but it can be a reason to go for v3.

Edit: I just realized that grickmin needed this for the 20 event competition. I couldn't narrow it down to less than four events (the fifth 'Esc to quit' one doesn't count, as it's not part of the feature). If you alerady have a 'start of frame' event in your application you can merge the one from this example with yours. Thus, 3 more events would be needed to support this feature. That might be a lot though if 20 is all you have.
