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.
