convert: deprecate --authors in preference for --authormap
This aligns the authormap option with the other three mapping options.
The old --authors option is still supported and 'hg help convert -v'
will still show it.
patchbomb: show prompt and selection in non-interactive mode
Akin to
01ada7b1861d for the custom patchbomb prompt.
patchbomb: use ui.promptchoice for diffstat to allow localization of choices
The extra check for ui.interacive from patchbomb's prompt function is not
needed here.
Format boolean prompt as in filemerge.py.
