This tries to make our code a bit more compliant with our code formatting
conventions. For future use, this is the command I used:
git ls-files "*.cpp" "*.h" | xargs sed -i -e 's/[ \t]*$//'
The only real way to pause the game is to take over the event loop, which is a little sad... Also fixed a possible crash when loading an image that was to big, by only rendering when we have _init set.
