Actually cache something when CacheLocalizedName is called. 

Before its name was a lie, since nothing was cached.

Another boolean was added because getting the localized name could fail, and we
don't want to pointlessly try again, so relying on fHasLocalizedName won't work
for that.

Since in my tests this was getting called up to 4 times per application when
opening the Deskbar Application menu, this caching should speed that up a bit,
at least when this file name translation feature is turned on.
