Mutations delete button.

[Peter]

A button/option to delete all mutations all bots had. Simular to save without mutations but then if mutations-list tend to go too high or after a certain time. Or just an option to disable remembering the mutations.

The reason, I find big performance issues with high listing of mutations. I had a sim running at 0,2/0,3 cyc/sec. After saving the sim without mutations and loading I get a speed of ~2,5cyc/sec.

Good suggestion.   I'll put this on the list.  The way mutation history is saved currently leaves a lot to be desired.  If I spend some time on this, I can probably get rid of any perf penalty associated with mutation history, but running without it would still improve working set.  I'll take a look at this.  I plan to do some profiling and other perf work over the next few weeks anyway.
