Bug#184816: cdebconf-newt-udeb: Newt frontend should indicate the question priority

[Petter Reinholdtsen <pere@hungry.com>]

Package: cdebconf-newt-udeb
Version: 0.32

The frontend should display some indication about the question
priority.  This is included in later versions of debconf, and I
believe we should have them in cdebconf as well.  I found this
argument in the debconf changelog for version 1.1.12:

  * Added priority sigils to the readline frontend. If you don't like
    the smileys, put Smileys: false in debconf.conf. To disable sigils
    entirely, use Sigils: false. I will implement smiley customization
    for $25. (Ads in a changlog -- you saw it here first :-P)

    Besides looking cute, the intent here is to make it obvious what
    priority a question is being asked at, to help combat priority
    inflation. Varying types of sigils will be added to the other
    frontends as well.

The debconf dialog frontend displays the following text in front of
the title to indicate priority:

  [.]  - low
  [?]  - medium
  [!]  - high
  [!!] - critical

It also have the option of displaying the following:

  |-)  - low
  :-)  - medium
  :-!  - high
  =:-O - critical

(I found the indicators in /usr/share/perl5/Debconf/Sigil/.)
