difftool now supports difftool.prompt so that users do not have to
pass --no-prompt or hit enter each time a diff tool is launched.
The --prompt flag overrides the configuration variable.

This prepares 'git-difftool' and its documentation for
mainstream use.
'git-difftool-helper' became 'git-difftool--helper'
since users should not use it directly.
'git-difftool' was added to the list of commands as
an ancillaryinterrogator.
