[feauture request] changing fonts of memory editor/cheat table

[DHLF]

Maybe it is too obvious but i was unable to change the fonts using debian 10(kde environment).

Using 4k resolution it is nice to see so much at once(I forced the window size of the memory editor manually to full height) but the text-size could be a little larger..

Also the font of the cheat table is not a fixed width font.

So "ten fullstops" have a different width than "1234567890" which breaks somehow the layout(of the description part).

Either the fonts are now hard-fixed or I was using another distro(Mint?) before which accepted changing the fonts.

Offtopic but..
Again the speed increase(from .17 to .18dev) is very sweet! Thanks a lot!!
