Added renamed aes220_Package_V1.2.vhd file and removed the 1.2.0 versions of the vhdl files

Renamed the package file from V1.2.0 to V1.2 as it not going to get patched since it only contains the procedures calls.
If it does have to get patch then its minor revision number would have to be increased.
aes220_Programmer now using API

The aes220_Programmer was using directly the C++ files used to create the API rather than the API itself (libaes220.so).
The programmer now offers two versions:
A command line program: aes220_Programmer.cpp
A GUI program: aes220_ProgrammerGUI.cpp
