macGui: fix bug in Advanced x264 option widgets

Modify the test to see if an optName already exists to avoid conflict with similar name patterns in the -X264AdvancedOptionsChanged: method where we test for the presence of the optNameToChange in the existing string.

This change starts on line 2215.
