FlexxCpu version 05 rev. B released

Changes in this new release are these:
Fixed some bugs existing in its simulated memory during the writing in ram, video memory, ecc...
Now the writing in the simulated memory is totally safe except for CPU registers, I am trying to fix it in the next release(!)
Fixed a bug during the viewing of illegal opcode error.
Fixed a bug during the change of the program counter to avoid exceeding the memory limits.
Fixed a bug when writing chars in video memory that in some cases it may lock out the simulator.
Added the ability to change the color of the text editor with the possibility to choose between 10 combinations, press the F9 key.
Added the possibility to change the format of displayed data when the monitor is active.
The simulator now remember the x position of the cursor when re-entering in text editor,
press <C> to save configuration.
The speed of the simulator is decreased due to the memory controls added to increase
the safety of writing into the simulated memory.

Known bugs or limitations:
Same as Rev.A.
