styled text advance

StyledTextAdvance #
Text widget with formatted text using tags. Makes it easier to use formatted text in multilingual applications.
Formatting is set in the text using xml tags, for which styles and other behaviors are defined separately. It is also possible to insert icons and widgets through tags.
You can set the click handler for the tag, through a tag definition class StyledTextAdvanceActionTag.

Line breaks #
By default, line breaks are not ignored, all line breaks \n are automatically translated into the <br/> tag. To disable this behavior, you can set the newLineAsBreaks parameter to false and insert the <br/> tag where you want to break to a new line.
