Access violation error in all overloads of SumOfLogs

[delphidabbler]

If a non-positive element of any array passed to SumOfLogs an exception is supposed to be raised. But we get an access violation instead. This is because the code is:

raise SysUtils.EArgumentOutOfRangeException(sNotPositive);

instead of

raise SysUtils.EArgumentOutOfRangeException.Create(sNotPositive);

i.e. the Create method call is missing!

This bug became apparent while implementing issue #31.

The fix has been completed on a local repo and will be pushed when issue #31 is pushed.
