Changes filehash to always be 16 characters

Filehash is a u64. Most of the time it is 16 characters,
but if the leading digit is a 0, it becomes 15 characters.
e.g. 0x0fffffffffffffff -> fffffffffffffff instead of
0fffffffffffffff. This changes it to format with leading zeros.
Which makes writing code to extracting the hashes more predictible.
