commit: RTF import list improvement

[Matti Picus]

I fixed the list import so that it seems to parse a format string from the 
RTF leveltext keyword.  I also change a bunch of member variables so they 
start with m_

Still to do:
I want this:  But I get:
1 One          1 One
   (a) One-a      (a) One-a
   (b) One-b      (b) One-b
2 Two          2 Two
   (a) Two-a      (c) Two-a
   (b) Two-b      (d) Two-b

Thanks to Martin Sevior for being patient with me.
