Replace SVGFilter using SVGIO

Target of this change is to get rid of the SVGFilter
in current LO which is based on the standard-ODF importer
using it's functionality by passing in/handing over
temporary created XML-Stream-Data.

First step is to alternatively import the given SVG
file to a newly created Document and to strip the
existing Filter-Code.

Adding the first prototype of the changed import. It
is capable of importing the given SVG to the created
Draw/Impress document. It adds the SVG which gets imported
by SVGIO as GraphicObject. It adapts sizes and positions of
Page and GraphicObject to have a smooth import.

Adding stripping of SVGFilter and used ressources. Done
as deep as possible, hopefully all places found.

Adapted now to create an Impress document. Also added needed
adaptions to PageSize(s), including layout and PresObj stuff
to make all MasterPages/LayoutPages work correctly.

Added reaction on empty SVG. This is needed since the
PageSize is adapted to the Graphic. With empty Graphic
a Size(0,0) results and this goes wrong.
