Added API allowing user to choose settings at runtime - replacement of PR#49 (#51)

* Adding in FF_SDDiskInitWithSettings optional initialization to support runtime initial mounting options.

* FAT-#50: Fixing duplicate definition of st_atime, st_mtime, st_ctime for linux.

* Fixing formatting with diff provided using uncrustify.
