Bug #664539 fix.

This fix was already done by Roman. But the escape_data dict cache was
posing problem in specific complex case. (Notably in
collective.recipe.template tests).
To keep the last fix, we would have to change every method of Options
class.

This fix does not use escape_data dict cache. This way, it allow
a simple working fix with minimal impact. Not breaking backward
compatibility.
