1. wxStaticLine implemented (generic (ugly) and MSW versions)
2. wxTextDialog looks fine under MSW again 3. startup tips added: code, sample, docs 4. read-only text controls don't participate in TAB traversal git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@2919 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
