Disk cache: For an AppCache, now we only update the

LRU list when an entry is created. This means that
we don't update the list anymore when an entry is
accessed, even if we are writing to the entry.

The general idea is that now we should be able to
open an AppCache and read from it without modifying
the contents of the cache, so that if the browser
crashes, we won't find "dirty" entries to discard.

By minimizing writes to the LRU list, we reduce the
chances that the list will get corrupt beyond the
point where we cannot trust it anymore if the whole
system crashes (and not just the browser).
