tdf#115639: Align right/center with trailing spaces the same as MS PowerPoint

* Add HoriAlignIgnoreTrailingWhitespace compatibility option.
** For MSO file formats it is set to true
** For ODP format it's set to false by default
** The flag is saved to ODP format as user data if the document
comes from an MSO format.
