[Etoys] Key generation

[Bert Freudenberg]

When starting etoys for the very first time, a crypto key is  
generated. This takes about a minute on the laptop. It's  
particularily frustrating because the counter does not stop at 100%  
but goes well beyond, everyone would think it does not finish at all.

Could we postpone key generation to the time it is actually needed,  
rather than first start? I guess the reason to do it this way is  
because of the sandbox? Can we do something to avoid that delay? Do  
we need the key at all?
