mc/src/widget.c
Slava Zanko 14be06d050 Reorganize work with files. Fixed permissions of files in mc home dir. All file names now accumulated into src/fileloc.h 
* Added common functions for work with backups of main config files.
 * Fixed permissions of ~/.mc/ini;
 * Fixed permissions of ~/.mc/filepos
 * Fixed permissions of ~/.mc/hotlist
 * Fixed permissions of ~/.mc/Tree
 * Fixed ownership for ~/.mc/hotlist file
 * Changed definitions of config files. Now used constants from src/fileloc.h

Also, added ability for change mc user home dir. Just type:
{{{
make CFLAGS='-DMC_USERCONF_DIR=\".mc2\"'
}}}

And you will have different config files (very usefull for testing or development).
