   *  - Changed over all demos, drivers and internal functions to use the current frame number over the Start of Frame flag where possible
   *    to free up the Start of Frame flag for interrupt use in the user application
+  *  - All project makefiles now correctly clean intermeditary build files from assembly and C++ sources (thanks to Daniel Czigany)
