Fix network connection timeouts and security detection

- Fixed detectSecurity() where WPA2 (0x100/PSK) and WPA3 (0x400/SAE)
  flags were swapped, causing NM to reject connections silently
- Added missing AP path to AddAndActivateConnection call
- Added critical connection settings: UUID, interface-name,
  autoconnect, permissions
- Changed init() to fail fast with logger.Fatal instead of
  silent failure on NM connection error
- Added auth-alg and psk-flags to WPA/WPA2 security settings

+# uuid ![build status](https://travis-ci.org/google/uuid.svg?branch=master)
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](http://tools.ietf.org/html/rfc4122)
+and DCE 1.1: Authentication and Security Services. 
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid).  It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice.  One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).
