Make preset searchs ignore accents

[naoliv]

In Portuguese if we press F3 and type estacao we can't find anything, since the proper word is estação

It's much easier to search estacao however, without typing the accents.

Could JOSM always display the results regardless the user using an accent or not? (by internally replacing every accented char by its equivalent and then searching using only non-accented words)

ie, if we type estacao or estação we should see the same preset result.
