french translation of cheatsheets page

Hello,

I haven’t translate the "infix sugar" because i doesn’t undertand what’s does it mean with the example.
(parens is the abbreviation of parenthesis or bracket ?)
(for : sole member of the Unit type  ; can be , in other word, could be understand as  « empty member of the Unit Type »  ?)

Oh, I forgot an important thing, The cheatsheets-sidbar.txt in _includes :
this terms can be translate in french :
Contents => Sommaire
Other Cheatsheets => Autre Antisèches
About => A Propos

The last loop prints the two about message, the english and the french one.

Thanks for all, 

Benoît
