Blacklisting rules

From the documentation I understand that the supported method of picking a rule subset is to copy the wanted rules into a directory and changing the rule search path.

This whitelisting approach has the disadvantage that when new rules are added to OCLint, someone has to manually find out about them and add them. An additional blacklisting approach (like clang's -Weverything) would allow having as many rules enabled as possible.

A possible solution would be a command line parameter with the name (or regexp) of rules to be ignored, another would be a config file. I'm willing to work on this, if it's deemed worthy of inclusion.
