massive step towards QGraphicsView being separated from libplasma

Browse Source 
* remove extenders (never panned out, used by exactly two components that we can find .. anywhere)
* move animations to libplasmagqv
* schedule js anims to be put into the js scriptengine
* move all QGraphicsProxyWidgets, except for IconWidget which is still used by PopupApplet, into libplasmaqgv
* create a subclass-able private class for Applet

TODO: move out icon widget, address FIXMES in graphicswidgetappletprivate.cpp and decide how to register the "right" private class for instantiation in Applet ctors

/**
* @class Extender plasma/extender.h <Plasma/Extender>
*
* @short Extends applets to allow detachable parts
*
* An Extender is a widget that visually extends the normal contents of an applet with
* additional dynamic widgets called ExtenderItems. These ExtenderItems can be
* detached by the user and dropped either on another Extender or on the canvas directly.
*
* This widget allows using ExtenderItems in your applet. Extender takes care of the presentation
* of a collection of ExtenderItems and keeps track of ExtenderItems that originate in it.
*
* The default Extender implementation displays extender items in a vertical layout with
* spacers that appear when dropping an ExtenderItem over it.
*
* If you wish to have a different presentation of extender items, you can choose to subclass
* Extender and reimplement the extenderItem* events and, optionally, the saveState function.
*
* To use an Extender in you applet, you'll have to instantiate one. A call to extender() in your
* applet will create an extender on your applet if you haven't got one already. Every applet can
* contain only one extender. Think of it as a decorator that adds some functionality to applets
* that require it. Never instantiate an Extender before init() in your applet. This won't work
* correctly since a scene is required when an Extender is instantiated.
*
* As soon as an Extender is instantiated, ExtenderItems contained previously in this Extender are
* restored using the initExtenderItem function from the applet the items originally came from. For
* more information on how this works and how to use ExtenderItems in general, see the ExtenderItem
* API documentation.

/**
* @class ExtenderItem plasma/extenderitem.h <Plasma/ExtenderItem>
*
* @short Provides detachable items for an Extender
*
* This class wraps around a QGraphicsWidget and provides drag&drop handling, a draghandle,
* title and ability to display qactions as a row of icon, ability to expand, collapse, return
* to source and tracks configuration associated with this item for you.
*
* Typical usage of ExtenderItems in your applet could look like this:
*
* @code
* if (!extender()->hasItem("networkmonitoreth0")) {
* ExtenderItem *item = new ExtenderItem(extender());
* //name can be used to later access this item through extender()->item(name):
* item->setName("networkmonitoreth0");
* item->config().writeEntry("device", "eth0");
* initExtenderItem(item);
* }
* @endcode
*
* Note that we first check if the item already exists: ExtenderItems are persistent
* between sessions so we can't blindly add items since they might already exist.
*
* You'll then need to implement the initExtenderItem function. Having this function in your applet
* makes sure that detached extender items get restored after plasma is restarted, just like applets
* are. That is also the reason that we write an entry in item->config().
* In this function you should instantiate a QGraphicsWidget or QGraphicsItem and call the
* setWidget function on the ExtenderItem. This is the only correct way of adding actual content to
* a extenderItem. An example:
*
* @code
* void MyApplet::initExtenderItem(Plasma::ExtenderItem *item)
* {
* QGraphicsWidget *myNetworkMonitorWidget = new NetworkMonitorWidget(item);
* dataEngine("networktraffic")->connectSource(item->config().readEntry("device", ""),
* myNetworkMonitorWidget);
* item->setWidget(myNetworkMonitorWidget);
* }
