Amount's default show instance hid important details, making eg test
failures hard to understand. Showing full detail required increasing
the debug level which was inconvenient.
Now it has a single show instance which shows more information, is
fairly compact, and is pretty-printable with pretty-show.
Ellipses (..) in the output indicate where fields are
- not shown in full detail, and/or
- shown in pseudo syntax (double quoted) to work with pretty-show.

MixedAmount's show instance is unchanged, but showMixedAmountDebug
is affected by this change:
ghci> putStrLn $ showMixedAmountDebug $ Mixed [usd 1]
OLD:
Mixed [Amount {acommodity="$", aquantity=1.00, aprice=, astyle=AmountStyle {ascommodityside = L, ascommodityspaced = False, asprecision = 2, asdecimalpoint = Just '.', asdigitgroups = Nothing}}]
NEW:
Mixed [Amount {acommodity="$", aquantity=1.00, aprice=, astyle=AmountStyle "L False 2 Just '.' Nothing.."}]
