* getSVG provides new style parameters for every kind of line:
V, V0, V1, H, H0, H1.
* Old line width parameters are removed. The style parameters
can be used instead.
* A style is a map container for svg attribute keys and values
(string, string).
* The Python interface is updated to offer the new style parameters
accordingly as a dict.
* Because there are many parameters on the function call now,
the Python interface supports keyword parameters.
* Update ArchSectionPlane to take advantage of the new style parameters.
This simplifies the code. String replacements could be removed
(done in a later commit).
* FeatureViewPy.cpp is – to my knowledge – the only function that used the
old line width parameters. I rewrote it to use the new style parameters.
* Uses DXF algos of the Drawing module instead of the Draft dxf library
* Uses a DXF template with the same name as the SVG template, if existing
* Only Draft, Arch, Part and Annotation views are currently supported
* Drawing module's projectToDXF() now returns only a fragment instead of a full DXF file
