Fixed cppChecker reported issues

1. Removed unused variable/code
     smarthighlighter.cpp, Babtgrid.cpp, shortcut.h, ImageListSet.h

2. Member variable not initialised in ctor
     ShortcutMapper.h, FileBrowser.h, ProjectPanel.h, TaskList.h, VerticalFileSwitcher.h, WindowDlg.h, lastRecentFileList.h

Closes #3478
