Changed notifications sync protocol
Fixed unserialization of NotificationId
Fixed a bug on Device.addPlugin introduced in commit 76c9def95b85cb0e336b89c3f1bdfd2042465f04, because onCreate was not executed in the main thread
+ MprisActivity now tries to reconnect to the plugin when there is a new connection,
just in case the new connection replaced the old one (the plugin would have been reloaded)
Now plugins are almost self-contained (PluginFactory still needs to know about them)
Regression: Plugins settings page does not work
Now plugins that fail to load can display a message to the user explaining the problem
Clipboard plugin now compares if content has changed before sending it
Plugins:
Moved plugins from BackgroundService to Device and adapted as needed
Plugins now implement their own broadcast receivers, instead of using a global one
Renamed ServiceLauncher to KdeConnectBroadcastReceiver

Interface:
Started new GUI (uses ActionBar and other Android 4.0+ widgets)
Mpris and Plugin Settings activities are now per-device
Removed SettingsFragment in favor of SettingsActivity (for now)
Removed CompatClibpoard
Added a class to convert internal phone name to human-readable names.
Persistence:
BackgroundService now stores a list of know (paired) devices
Device now stores its name, trusted state and plugin list
Added setTrusted and trust/untrust logic to Device
The Settings activity now reads/writes the plugin settings from/to Device
