commit 9fe8190364d27a538efa3928d2166b09e1cef2d5
Author: Jean-Marc Lasgouttes <lasgout...@lyx.org>
Date:   Mon Jul 24 00:21:43 2017 +0200

    Make "devel mode" configurable at run time
    
    Traditionally LyX behaves differently when the directive DEVEL_VERSION
    is defined at compile time. This covers
    * more detailed description of current position in status bar
    * the help files are open in read/write mode
    * more detailed debug output in the View Source panel
    
    This patch introduces the new function devel-mode-toggle that allows
    to use devel mode in stable releases, and vice versa.
    
    The information is saved in the session file. The default is to
    disable devel mode.
    
    Remove all traces of DEVEL_VERSION in autoconf and cmake
