Override default NSFileProtection handling
Adjust indentation

Minor detail, but over time some macros have lost proper indentation.
Merge pull request #287 from rivera-ernesto/indentation

Adjust indentation
Removed all the "C" log macros (as suggested in #220). By replacing sel_getName(_cmd) with __PRETTY_FUNCTION__, there is not need for the separation of Obj-C and C macros.
Updated the Mobile libtest project to demonstrate that it's working (had to use a formatter so the function/method names are used).
