Fix bug 3450:
http://bugzilla.lyx.org/show_bug.cgi?id=3450 * ControlMath - new MathSymbol struct that summarize the symbol attributes (including font and fontcode) * QDelimiterDialog: - make use of the new MathSymbol for the ListWidget. - store the latex name in the tooltip instead of lookup for it. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@17786 a592a061-630c-0410-9148-cb99ea01b6c8
