All brush styles exported by QSvgGenerator look like SolidPattern

QSvgGenerator::savePatternBrush() wrongly adds a semicolon (probably a typo) after url name (line 247 in file qsvggenerator.cpp) making any brush style other than Qt:: NoBrush to be rendered like Qt::SolidPattern in any SVG viewer. The bug does not affect Qt <= 5.5.1, but I cannot test with other Qt release between 5.5 and 5.9.

Furthermore, brushes exported by QSvgGenerator cannot be displayed correctly by QSvgRenderer. The error message is for example: "qt.svg: Could not resolve property: fillpattern13_ff0000".
