Make explicit svg height and width declaration optional

Add a config property for setting where to include the width and height declaration items in svg.charts.graph.start_svg().

A very simple patch (because I'm too lazy to look up etree) would be to include a class attribute explicit_size = false then in the start_svg section:

#!python

if self.explicit_size:
    self.root = etree.Element(SVG+"svg", attrib={
            'width': str(self.width),
            'height': str(self.height),
            'viewBox': '0 0 %s %s' % (self.width, self.height),
               '{http://ns.adobe.com/AdobeSVGViewerExtensions/3.0/}scriptImplementation': 'Adobe',
            }, nsmap=NSMAP)
else:
    self.root = etree.Element(SVG+"svg", attrib={
            'viewBox': '0 0 %s %s' % (self.width, self.height),
            '{http://ns.adobe.com/AdobeSVGViewerExtensions/3.0/}scriptImplementation': 'Adobe',
            }, nsmap=NSMAP)

Add a hook to allow customization of attributes added to the root SVG element. Fixes #4

Oh. I see now the code does include those attributes. You want a way to suppress them.

Is there any reason not to include always the size attributes?
