Win32: Only show the resolution information at certain times.

It's way too "talkative" as it is.

Previous behaviour:
* It would display resolution information twice every time you exit or enter fullscreen
* It would display when you resize the window, resulting in dozens of messages being shown
* It would display when you maximize the window
* It would display when you start a game/exit the pause screen

It now displays(one time per click/press, unless the following are spammed, of course) when:
* Selecting a resolution size
* Selecting a window size
* Exiting the pause screen after being in the game settings screen
