This uses the same metric to show the spinner in the contact list and
the plasmoid.

It stops it spinning eternally and saves plasma-shell's CPU rendering a
spinning thing forever.

This patch is a minimal change that I want to put into 15.04 that
doesn't  alter API.

We actually don't care if say the presence message differs, we're only
interested in the actual presence type

This should fix an infinite busy wheel on the applet in some cases

Things like

Presences:
     Current: offline
   Requested: offline
    Changing: yes

are not unusual and this makes the applet keep spinning forever in such
cases. Better to simply compare requested and current presence.

Properly export all targets with a config file.
Generate export files for all the internal libraries.
Use nicer target names.
Make dragging of dependencies more fine-grained.

Exposes PresenceModel on QtQuick and registers the related types
Makes it possible to interact with the PresenceModel from QtQuick by
exposing some methods and properties.
Makes the GlobalPresence use KTp::Presence for consistency.

Notifies about presence changes when presence changes.
Exposes the icon so that it can be displayed on UI, Tp::Presence is not a
QObject so it can't be introspected.
Name the QtQuick binding the same way as the class name, otherwise it's
confusing.

This adds a PresenceManager class to Declarative that can be used
from QML to get and set global presence.

REVIEW: 116880

Change the global current presence algorithm to use the presence
same as global requested presence if there is at least one account
with such presence, otherwise it will fallback to the old algorithm.

statusMessage was missing before and it should be 'or' instead of 'and'.
Now it's the same as in onCurrentPresenceChanged().
This fixes presence saving in the case that only the presence message
changed.

Change m_currentPresence even if the Tp::Presence::statusMessage() was changed. Also couple of minor fixes.
