No global configuration

[Dmitry Sapozhnikov]

There is only per user configuration option.

This is how it should be:

• Stop using envvar VTM_CONFIG - use vtm -c $VTM_CONFIG instead.

• If the -c option is specified then only the specified config should be used.

• Otherwise load combination of global_config + per_user_config:
  global:

  • win32: %programdata%/vtm/settings.xml
  • posix: /etc/vtm/settings.xml

  per user:

  • win32: %userprofile%/.config/vtm/settings.xml
  • posix: ~/.config/vtm/settings.xml
