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. Task-number: QTRD-1912 Change-Id: I8fa56df56fd656e2a3e427eff4abf3481435eec7 Reviewed-by: Mika Salmela <mika.salmela@digia.com>
