tdf#154248 sd: change multiline field wrapping

Modified ImpEditEngine::CreateLines and ImpEditEngine::Paint
to wrap multiline fields (hyperlinks) to wrap better:

Multiline hyperlinks can start/end in the middle of a line.
like this:
text hyperlink-start
hyperlink-line2.....
hyperlink-end text

Start of the lines of the multiline hyperlinks now follow the line
start (for example if the 1. line has a bullet/indent, and the
2. line does not then the multiline hyperlink 2. line will start
where normal 2. line would start)

Changed the way how fields wrapped while editing.. (we didn't split
fields into lines, when its textbox is edited, but now we do)
This way it is more a WYSIWYG editor. (when we edit, we see what
we will get)

Changed the constant reference rLine to non-constant pointer
pLine, because this hack change the actual line to the next line
at the end of a muliline hyperlink, so the algotithm will
continue calculating with the next line, as if it would be still
the previous line.
