Storage permission might be unnecessary

[rllola]

ZeroNet is working fine for me without it enabled, and I've never noticed a problem with it disabled. Multiple times I've enabled it, but never noticing a need to. Now, I've been using ZeroNet with it disabled ever since the IPv6 pull request, because I reinstalled it since then. The permission is likely for accessing files outside ZeroNet's directory, not for accessing ZeroNet's directory.

I think it's fine to remove it, it was just there because I copy & pasted it from someone else's code and never gave it much thought.
