[PATCH] improve Objective-C filetype detection

[Kazuki Sakamoto]

Hi Bram,

I've created a patch to improve Objective-C filetype detection in ".m"
and ".mm" file. Could you check the patch?

Modern Objective-C code uses "@import" instead of "#include" or "#import".
http://clang.llvm.org/docs/Modules.html#objective-c-import-declaration

Regards,
Kazuki

Problem: Fail to detect modern Objective-C code.
Solution: Add @import detector
