FlexxCpu version 05 rev. D released

This is a minor update.
There was a problem that was preventing the reading of video memory, this error was corrected.
The MOV opcode has been changed with name STM as the opposite to LDM.
I implemented the reading from the 0x60 input port through the INP opcode, see Flexx_MiniGame_Test.asm
I greet you and thank you.
