 If you open up a directory containing thousands of files, it currently computes the cache filename and checks for the cache file on disk immediately for each immutble file in that directory.  With this patch, it delays those steps until you try to do something with an immutable file that could use the cache.

[Tolerate unknown URI types in directory structures. Part of #683.
Brian Warner <warner@lothar.com>**20090703010749
 Ignore-this: afd0e15e2e39d3b87743ec7ccd87054d
 
 The idea is that future versions of Tahoe will add new URI types that this
 version won't recognize, but might store them in directories that we *can*
 read. We should handle these "objects from the future" as best we can.
 Previous releases of Tahoe would just explode. With this change, we'll
 continue to be able to work with everything else in the directory.
 
 The code change is to wrap anything we don't recognize as an UnknownNode
 instance (as opposed to a FileNode or DirectoryNode). Then webapi knows how
 to render these (mostly by leaving fields blank), deep-check knows to skip
 over them, deep-stats counts them in "count-unknown". You can rename and
 delete these things, but you can't add new ones (because we wouldn't know how
 to generate a readcap to put into the dirnode's rocap slot, and because this
 lets us catch typos better).
