Changes "Blacklist" to "Blocklist" (see for details).
Adds explanatory text to the blocklist dialog, so the users sees that keywords have to be comma-separated when they are actually typing them into the field, not before.
Removes a period . in settings_enable_entry_swipe_description to be consistent with all other settings descriptions.
