pylint 1.4.3 version fixes

pylint 1.4.3 version fixes

Pylint 1.4.3 completely stopped recognizing the star-args condition.
In order to avoid pylint error with > 1.4.3 stop caring for star-args
and add cmdline option to ignore those errors completly so older pylint
versions are happy too.

Also fix type() vs isinstance() checks, isinstance is generally a more
correct approach to check for classes.

In some 'admin' files the type() -> isinstance() fix required to invert
the order in which ComplexList and MappingList are checked as the latter
is a subclass of ComplexList, so it needs to be checked first otherwise
the check for isinstance(option, ComplexList) matches for both and the
code stops functioning properly.
