Marcus had written up workbench style widgets inside the two external helper programs requestchoice and executecmd. This ports the code over to libami. Note that there isn't a generic gadget or collection of gadgets yet - this is purely a refactor of the code, and the upcoming commit that migrates requestchoice/executecmd over to use them just handles them directly via xlib like they have always done.
