[Pharo-dev] [Pharo Trick: #0009] 'Enable halt/inspect once' button

[btc]

When I have a 'self haltOnce' breakpoint that I am activating often, 
going "World > System > Enable halt/inspect once" each time is 
annoying.  So using the Duplicate Halo on the menu item, I drag it onto 
the background so that it acts like a button.
