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]*$//'
This is used to provide default implementations for createConfigWriteStream
and createConfigReadStream, which can be used by most backends.
Note that backends can still override createConfigRead/WriteStream;
this could be useful if settings on some port are not stored in a
regular file (think 'Windows registry', for a hypothetical example).
Formerly SdlEventManager was a subclass of DefaultEventManager but did not
really have anything in common with the idea of our EventManager interface.
Now I made a new object SdlEventSource which only subclasses EventSource
and which is responsible for obtaining events from SDL (and processing them).

This fixes a hack for resetting the graphics scale to x1 when starting games that have a large screen size. The SDL graphics manager should now scale back to x1 without changing the current scaler in use, as well as the OpenGL graphics manager.
