PPTParagraphObj: fix problems in previous commit:

- check for a null List element is actually check for valid index
- there may be any number of character properties for every paragraph,
  so need to pass in 2 parameters to PPTParagraphObj ctor
- PPTTextObj::PPTTextObj: nIdx became n in one place
- PPTTextObj::PPTTextObj: n++ dropped in one place
