wrap more fuctions that work with FILE

SlowRollinLow reported that SuperHehagon crashes when the game is
completed instead of showing it's ending, and it is an extremely difficult
game.. It turned out it does fwrite(..., stdout) on it's ending,
and that was not wrapped..

Wrap more functions to try not to disappoint people.
Still not all FILE users wrapped, but at least all likely ones
should be wrapped now..
Merge pull request #28 from notaz/stdio
