Alexandre Flament 1cfe7f2a75 [enh] settings.yml: add use_default_settings option
This change is backward compatible with the existing configurations.

If a settings.yml loaded from an user defined location (SEARX_SETTINGS_PATH or /etc/searx/settings.yml),
then this settings can relied on the default settings.yml with this option:
user_default_settings:True
