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.

d3f0a08f0d Report a failure and exit if type checking fails 
Type checking failures were previously not reported and the file was
silently ignored. This change will report the error and halt further
processing.

942f40acf5 Fix nosec to work as documented 
This commit fixes the nosec feature to check for '#nosec' instead
of 'nosec'.  This should help reduce false positives associated
with comments that have 'nosec' in them somewhere.

129be1561b Update error test case 
There were several issues with the error test case that have been
addressed in this commit.

- It is possible to specify a whitelist of calls that error handling
  should be ignored for.
- Additional support for ast.ExprStmt for cases where the error is
  implicitly ignored.

There were several other additions to the helpers and call list in order
to support this type of functionality.

- Add test cases to ensure correct behaviour
