Feature Request: Allow Upper/Lower Charset in Mem View

[paulhocker]

Provide a toggle to let developer switch between upper/lower case in the Mem view. This will let us make sure that the correct petscii is getting added without having to resort to decoding it manually.

added a flag for it in the memory view

The case setting is not working as I expected. I was hoping it would show the lowercase petscii values, instead it is showing question marks?
