Errors in HTML handling when making gridpack

[Zachary Marshall]

In 2.6.7, we see this error when making a gridpack:

cp: cannot stat 'HTML/run_01_decayed_1': No such file or directory
find: 'HTML/default': No such file or directory

It looks to me like that's coming from store4grid:

```
rm -rf HTML/default
cp -rp HTML/$1 HTML/default
for i in `find HTML/default -name "*_results.html"`;do
    sed s/$1/default/g $i | sed s/log.txt/default_log.txt/g | sed s/$1_$2/default/g > $i
done
```

The trick here seems to be that we've used MadSpin (by just providing a MadSpin card), so the events are moved over to run_01_decayed_1, but the HTML itself seems to still have a run_01 directory. I don't believe we're directly calling store4grid, but that this is called by MG5_aMC internally.

Did I guess the problem correctly, and could this be fixed in a future patch?

Thanks,
Zach
