[tor-commits] [arm/master] Moving glyph demoing to its own executable

commit 7b93874508050223d5ed36b67b889f1cbdfaa432

    Moving glyph demoing to its own executable
    
    Our curses glyph demo is a handly tool for curses development, but there's no
    reason for it to be part of our ui_tools. It's a script to demo curses'
    capabilities and only ever meant to be a reference during development.
