Added FPU_FFT example from STM32F4_xx_FPU_FFT
Broke out CPFLAGS in make file so each has its own line. (To add comments)

Changed FPU_FFT to blink LED based on how long it takes to perform each calculation 1000 times. Blinking should be related to performance then.

Ignore .depend files from EmBlocks.
Added common makefiles.

Updated Peripheral Examples to use common make files.
Removed unused common files.
