tdf#127166, tdf#123903 improve import/export of line styles

I have added import and export of prstDash line styles, for OOXML
and for binary MS Office formats. This includes:
Corrected Dot <--> Dash confusion, corrected some wrong defaults,
added support for hairlines tdf#127267, take care of treating
length 0 as 100%.

tdf#108064 has introduced some mapping from our standard line styles
to OOXML prstDash. I have removed that and implemented to export
our styles as custDash and recover them back on import. That way the
dashing looks initially the same in MS Office. I have removed the now
wrong test.

Binary MS Office formats have no custom dash styles AFAIK, therefore
I have not changed the export of our styles there, but only added
support for prstDash styles.
