Fixed the error when the 'memorial' dir was not found.

See this http://smf.cataclysmdda.com/index.php?topic=12936.15 topic, when there memorial dir didn't exist there was an error message creating the nested directories.

This should fix this.

Could we not just revert the original bad commit?

[Soyweiser]

Well, that doesn't implement the feature of different memorial dirs per world. Which was the reason I made the first pr.

[mugling]

We still have no way of testing these changes and given that the first PR was trivial yet still resulted in issues it's perhaps not encouraging to make further changes

When I noticed the problem on the forums, I asked a friend if she could test it on a win10 machine. (To reproduce the bug). While reproducing, I found the bug myself (on my win7 machine). So I could ask her to test it again on the win10 one.

I have tested it myself by removing the memorial dir. (Something I had not tested before, (assumptions, ass me etc)).

Testing if the dir exists and creating it if it doesn't should be pretty safe and shouldn't introduce other problems.

Asked my friend to test on win10. Works there as well. No error messages creating a world and suicide a char.
