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
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).
