Explicitly convert between nullable and non-nullable on OS X
Clang was complaining about implicit conversions between nullable and non-nullable NSString pointers. Adjusted our std::string -> NSString* conversion utilities to check for nil and return an empty std::string in that case. Replaced uses of [NSString stringWithUTF8String] with our STD2NSSTRING macro. Turned std::string <-> NSString* conversion macros into functions. Test-Information: Builds without the warning on OS X 10.11.3 and Swift runs without issues. Change-Id: I949f2f3332018391aead58ef362764f4b7955b01
