Swedish T1, 11- Flappy Bird
Update fuegos-artificiales.md

I've made ​​some changes following the latest model of the original English version.
Bugfix - Fruit1 is ignored when evaling win/lose
Bugfix: `1 != YES`, and `0 != NO`.
`NO` here refers to a constant, not a variable.

(NO) renders as a variable, which is not correct. Not sure if [NO] will
render as a constant (black text on white background) but hopefully.
