This fixes something that may be a bug in the dispatcher.

BUt I'm plugging it here in order to get a temp fix to Dan before
his presentation.
Cast fingerprint to int64 before we store it in db: fixes int-size
errors reported by cassandra.

It appears to me that int64(uint64_value) is bit-preserving. The
following two tests, inserted into StoreURLFetchResults, never produced
any output.

	var foo int64 = -1
	var bar uint64 = uint64(foo)
	if int64(bar) != foo {
		log4go.Error("PETE: Conversion error basic %d, %d", int64(bar), foo)
	}

	if uint64(int64(fr.FnvFingerprint)) != fr.FnvFingerprint {
		log4go.Error("PETE: Conversion error %d, %d", uint64(int64(fr.FnvFingerprint)), fr.FnvFingerprint)
	}
simplehandler: fix base url issue

simple handler wasn't properly dealing with directory URLs, like simply
`http://test.com`. Made it not try to create files for those, as there
is no good name to give them anyway.
