NS #1819 creates www.NetSurf.Cache when it is started.

NS #1888 (and higher) creates www.NetSurf.Misc when it is started.

Having moved Cache out of Resources, and set it to be 'seen' before
NetSurf, !Cache.Caches.Single.NetSurf has now been created, and data is
being written to it.

I think that previously, when Cache was in the default Resources, it was
being 'seen' after NetSurf, which was in 'Look at'. They are now both in
'Look at', Cache well before NetSurf.

Thanks for your help.
