Grant Murphy 9bc02396e8 Introduce entropy checking of string
This will hopefully reduce the number of false positives when it comes
to hard coded credentials. The zxcvbn library is used to calculate the
entropy of the string. By default the first 16 characters are considered
as doing the entropy check for strings much longer than that introduces
a fairly significant performance hit.
