Added board Nucleo-F411RE alpha status

1. the jpeg of NucleoF411RE is actually a copy of the NucleF401RE: TDB
2. the NUCLEF411RE.py and Makefiles are just cut and paste of the F401RE with appropriated changes about memory size. I intentionally left a reference to 'stm32f401.csv' since both boards really are described as the same in the User Manual. This said, it could be different with other boards/packages.
3. jsHardware.c has been modified by Geany removing ending spaces at various lines. This is a consequence of my working parameters, I have not seen any other differences but removed ending spaces (or tab maybe).
