bottom (or top) menus

[picobyte]

make some of the bottom buttons pull-up menus or put those on top. Features to implement:
File menu with Open / New / Save / Save as / Quit. Also visual mode variable viewer / editor.
Edit menu
View menu with Font (size, name), display style (instead of 'monokai'), language for spell checker

maybe more gui adaptations: https://lemmasoft.renai.us/forums/viewtopic.php?t=9812
