Date: Thu, 10 Jul 2014 02:02:59 -0300
Subject: Corrected some SC behaviour, special thanks to Rytech - Extracted
 some methods to check SC blocks - Fixed issue that when players couldn't
 attack they couldn't talk to NPCs with mob view id either

Follow up to ec51176326c6028630835538db67826281d34ffe, fixed minor typo
