Docview and IDE patch from Morag Hua with fix for bug #1217890

"Closing view crashes Python" plus some new features:

    New feature added to the IDE is 'Extensions'.  Under
    Tools|Options|Extensions, you can add calls to external programs.
    For example you can add a "Notepad" extension (under windows) that
    will exec Notepad on the currently open file.  A new "Notepad"
    menu item will appear under the Tools menu.
