Wrappers and iframes

Iframes can be misused to evade wrappers. Prior to 0.5, jShelter limited some wrappers but not all. To be fully protected, you should see [native code] as a body of all displayed functions. Note that you should see the same content even if you do not use any extension that modifies the calls. We want not to be distinguishable even if fully protected to limit fingerprinting.
