Added new headers to all the .cxx and .hxx files with updated
copyright information. Fixed the bug in StellaX where pressing the close button in the title bar would not call the MainDlg::Quit() method (and hence not save certain settings and free some memory). Cleaned up the formatting of most of the source code, which was honestly in such a sorry state that parts of it were difficult to read. Got rid of CSimpleString class and references that were no longer used. git-svn-id: svn://svn.code.sf.net/p/stella/code/trunk@318 8b62c5a3-ac7e-4cc8-8f21-d9a121418aba
