Added HTML support for various text items...
Added HTML support for various text items - HTML tags can now be used in chart titles, legends, and labels - '\n' does no longer cause line break in multi-line text items. HTML tag <br/> can be used for line break now. - Setting pen for axis titles and labels is deprecated - When setting brush for titles and labels, only the color is relevant - Logic for identifying label format specifiers was improved, so adding additional information to labels via label format string is now more viable.

\class QLineSeries
\brief The QLineSeries class is used for making line charts.
\mainclass
A line chart is used to show information as a series of data points
connected by straight lines.
\image examples_linechart.png
Creating basic line chart is simple:
\code
QLineSeries* series = new QLineSeries();
series->append(0, 6);
series->append(2, 4);
...
chart->addSeries(series);
\endcode
*/
/*!
\qmlclass LineSeries QLineSeries
\inherits XYSeries
The following QML shows how to create a simple line chart:
