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.
