Changes about accents

In order to make the taki zorai available at an international level, I think it is important to remove the use of accents (and of the ¨), to allow the writings for each keyboard.

Words concerned :
ayumé
mayumé
déna
ké
kéan
kakémono
né
réh
mazé
zénui

chaï
daï
kwaï
laï
moaï
zoraï

And all words based upon those.

Grammar : the passive form -é
gai -> gaié for example

I decided to supress the accented characters é and ï (replaced by simple e and i), and replace the final -é by a final 'e, which should be grammatically more noticable and understandable.
