Added support for iPhone to MGMFFmpeg. Updated settings in Theme Tester. Updated settings in VoiceMac for the Theme Manager. Added the ability to hide icons in themes. Added the ability to change the font in themes. Fixed issue in MGMAddressBook where getting group members is not accurate. Made it so SIP addresses and Email addresses would not be recognized as phone numbers. Added support for 2 step verification. Added the ability to reload the user phone numbers. Added the ability to place the next message at any point in the previous message. Added the ability to do css based on the class of the message view with %MESSAGECLASSES%. Added the ability to get the codecs available and change the top codec in MGMSIP. Made it stop ring back before hanging up. Added initWithRootElement: to MGMXMLDocument. Added initWithName: and initWithName:stringValue: to MGMXMLElement. Added initWithKind:, setStringValue:, and fixed issues with reading attributes value. Made MGMVoiceUser support 2 step verification API, reload the user phones when it becomes active, and display a message if there is no phone numbers in Google Voice. Fixed issue where Google Chat will not appear in the User Phones list. Added a 2 Step Verification Dialog. Added Codec selection in MGMSIPPane. Fixed issues with MGMMultiSMS where it wouldn't alert the user if the message was blank and it wouldn't make the text field non editable. Added support for new SMS protocol to MGMSMSMessageView. Added support in the FFmpeg install script to build for iOS. Added ability to compile for the Simulator only in the PJProject build script. Made iOS and Mac OS final path go to 2 different folders. Updated to Revision 3466 of PJProject.
