Subject: Add QCommandLineOption::Flags containing HiddenFromHelp and
 ShortOptionStyle

This patch adds a new option, QCommandLineOption::ShortOptionStyle, which helps
applications (such as compilers, so moc and now qdoc) which need to mix long-style
and short flags.

[ChangeLog][QtCore][QCommandLineOption] Added flags() and setFlags() methods.
Added ShortOptionStyle and HiddenFromHelp flags.
