503a607090 More overflow-avoidance. 
One source of overflow during testing was changing the denominator on a
max-precision number. If the numerator was clamped with a large denominator,
changing to a smaller denominator without rescaling created a number that
would overflow later when applied to a commodity with a different SCU. This
change re-scales numerators in those cases so that the overflows don't happen.

456e121930 Ensure random numeric denominator is the account SCU when creating splits. 
The lot creation and balancing code uses gnc_numeric_foo_fixed(), assuming that
all amounts in a split have the same denominator, the account's SCU. Ensuring
this when creating test cases prevents spurious failures.

b694df7202 Prevent overflow. 
LCD denom was equivalent to using rounding.denom, which is val.denom * 10.
If val.num was at the max # of digits that would overflow, so instead
fix val.denom and actually round the result; since we're adding
5/(val.denom * 10) to accomplish the rounding we want to truncate the result.

9d029d7f82 More realistic get_random_gnc_numeric() 
Increases the possible denominators to 1E10, but clamps the numerator to
1E13 * denom with 1E19 max. This is equivalent to $1E8/1 US in
Indonesian Rupiah, the currency with the lowest per-unit value in the
world at the time of this commit.

22490a37ab Fix build-time hard-coded path introduced by the guile2 compile changes 
These changes hardcoded the standards-reports path at build time.
On Windows and OS X the final path is only known at installation time.
So after installation the build-time hard-coded path would be invalid and
the standard-reports directory could no longer be found.
