QuickCheck added an Arbitrary instance for CTime aka EpochTime. However,
while git-annex's instance disallowed times before the epoch, QuickCheck's
does not. So, rather than using its instance, convert from an Integer.

For some reason this was working w/o a cast before, despite POSIXTime etc
being newtypes. It stopped working with the new QuickCheck:
Utility/QuickCheck.hs:31:33:
No instance for (Integral POSIXTime)
arising from a use of `arbitrarySizedIntegral'
Possible fix: add an instance declaration for (Integral POSIXTime)
In the first argument of `nonNegative', namely
`arbitrarySizedIntegral'
In the expression: nonNegative arbitrarySizedIntegral
In an equation for `arbitrary':
arbitrary = nonNegative arbitrarySizedIntegral
A very haskell commit! Just data types, instances to serialize the metadata
to a nice format, and QuickCheck tests.
