Remove \title as a meta-command, and instead parse its argument inline using DocParser, similar to \section argument, as a single-line paragraph. Store the resulting Text instance to DocPrivate, so that generators can query a title Text from a Doc and output a formatted title. The benefit of this change is that formatting commands are now allowed within a \title argument. While typical formatting such as \c (code) or \e (emphasis) are discouraged in titles, \notranslate is useful in marking terms within titles to exclude them from machine translation. Keep Node::title() and Node::setTitle(), continue to use them for title strings such as in .index files, and for the purposes of searching for nodes using a title. Store a simplified string representation of the \title Text, with formatting removed, into the Node for this purpose. [ChangeLog][QDoc] Formatting commands such as \notranslate are now supported within page \title argument.
