Now 2.17 repaired.

Enough room made to add the support of QUARACTERDISPLAY which is next to do.

The Quaracter-display is almost working.
All but block change is OK.

Speed is almost the same as v216 and with the option to select fast or quaracter display it will be as quick as v2.17
but with more perfect screendisplay.

I have an idea to improve speed of quaracterdisplay so I hope to bring out 3.01 soon.
