[Lint] Update pylint rcfile

* Merge in pylint 1.6.4 rcfile changes.
 * Add future_builtins to redefined-builtins-modules ignore list. (should be pylint default!)
	- Removed pylint disable comments from files.
 * Rearrange disable section, comments must be at start of line but can be
   interspersed to highlight categories.
 * Conventions enabled:
	wrong-import-position
	wrong-import-order
