Make it possible to disable the file part of the flotsam asset cache
This matches the ability to disable the memory part This is controlled through the FileCacheEnabled parameter in FlotsamCache.ini Default is true, so existing installations are not affected. Improved fcache command feedback when various caches are disabled. Re-enabled test for flotsam cache with file caching disabled.
