Change apple llvm 8.0 - language for mixpanel plugin

[leandroz]

The https://github.com/samzilverberg/cordova-mixpanel-plugin needs this setting in order to compile, is there a template or example I can use to create the hook and then make it available?

Steps:

• open your project in xcode
• goto build settings tab
• scroll down to "apple llvm 8.0 - language"
• set "C language dialect" to be default
