Initial commit
Started mocking up the UI
Port knock sequence now persisted to shared prefs.
Integerated BetterPickers library.
Connection list populated from JuiceSSH connection list.
Now possible to define a port knock configuration on a per-server basis
Knocking working - i think I need to do something for port locking post-connection though as most knocking daemons don't automatically relock the port from what I can see.
Working, but missing some key features like widget/homescreen shortcuts.
