This meant to add a lot of dependencies to each plugin since we had
KDELibs4support as PUBLIC link meaning that anything linking against
kdeconnectcore was linking at the same time to mostly all frameworks.
Now each plugin has more or less its dependencies in the CMake some
still depend on KDELibs4Support.
For the mousepad plugin I needed to add a fixX11.h file that basically
undefines/defines again some stuff xlib has that conflcits with normal
C++ and Qt.
Before it was not conflicting because some lib within KDELibs4Support
was including this file, but now we have to do it ourselves.
Straight forward port from QJson to the native Json support.
As a note I have added 2 helper functions that make the code bit more
readable (object2qvariant and qvariatn2qobject).
Now protocol version is only sent once (in the identity package)
Removed "isEncrypted" bit, using type "kdeconnect.encrypted" instead.
NetworkPackage's decrypt and unserialize return false when find problems
Updated tests.
Fixed some bugs in the pairing process state machine
Keys are now stored in base64 in KConfig (was storing non-allowed chars)
Updated NetworkPackage tests to include encryption
Increased networkpackage version 1 -> 2
