Add '@chdk_version' control to script header to specify version compatibility, and display warnings on version checks.
Change Lua functions to return a boolean instead of an integer (get_raw, get_video_button, get_focus_ok, save_config_file, load_config_file, & set_mf).
Add Lua wrapper code so that above functions return integer value for 1.3 compatibility.
Add '@chdk_version' to standard scripts in build.

Remove version numbers stored in conf and camera_info structures (only used in module_load validate() function).
This moves the 'conf' structure to the BSS section which reduces the size of diskboot.bin by 2K (runtime memory usage is unchanged).
Fix gen_modelist_lua.sed to work on OS/X (extended regular expressions not supported)
