Use iconName instead of sending a fixed-size pixmap around, fix wording and use title
capitalization, more meaningful names in notifyrc, QStringLiteral and new style connect.

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.
The parent of the QDbusAdaptor has to be a Device, and now it was a
KdeConnectPlugin for the Notifications plugin.
Instead of passing the parent (that is actually a Device) to the
QDbusAdaptor as we were doing in the Battery plugin, I preferred to get the
actual Device from the KdeConnectPlugin, even though it needs a const_cast.
Ported using KDELibs4Support, for a smaller delta, so we can keep
developing on master until we decide not to.
At the moment, it builds and installs but tests don't pass because
of a QCA2 initialization problem I didn't manage to debug yet.
