/**
* The Browser Extension is an extension (yes, no kidding) to
* KParts::ReadOnlyPart, which allows a better integration of parts
* with browsers (in particular Konqueror).
* Remember that ReadOnlyPart only has openURL(KURL), with no other settings.
* For full-fledged browsing, we need much more than that, including
* many arguments about how to open this URL (see URLArgs), allowing
* parts to save and restore their data into the back/forward history,
* allowing parts to control the location bar URL, to requests URLs
* to be opened by the hosting browser, etc.
*
* The part developer needs to define its own class derived from BrowserExtension,
* to implement the virtual methods [and the standard-actions slots, see below].
*
* The way to associate the BrowserExtension with the part is to simply
* create the BrowserExtension as a child of the part (in QObject's terms).
* The hosting application will look for it automatically.
*
* Another aspect of the browser integration is that a set of standard
* actions are provided by the browser, but implemented by the part
* (for the actions it supports).
*
* The following standard actions are defined by the host of the view :
*
* [selection-dependent actions]
* @li @p cut : Copy selected items to clipboard and store 'not cut' in clipboard.
* @li @p copy : Copy selected items to clipboard and store 'cut' in clipboard.
* @li @p paste : Paste clipboard into view URL.
* @li @p pasteTo(const KURL &) : Paste clipboard into given URL.
* @li @p rename : Rename item in place.
* @li @p trash : Move selected items to trash.
* @li @p del : Delete selected items (couldn't call it delete!).
* @li @p shred : Shred selected items (secure deletion) - DEPRECATED.
* @li @p properties : Show file/document properties.
* @li @p editMimeType : show file/document's mimetype properties.
* @li @p searchProvider : Lookup selected text at default search provider
*
* [normal actions]
* @li @p print : Print :-)
* @li @p reparseConfiguration : Re-read configuration and apply it.
* @li @p refreshMimeTypes : If the view uses mimetypes it should re-determine them.
*
*
* The view defines a slot with the name of the action in order to implement the action.
* The browser will detect the slot automatically and connect its action to it when
* appropriate (i.e. when the view is active).
*
*
* The selection-dependent actions are disabled by default and the view should
* enable them when the selection changes, emitting enableAction().
*
* The normal actions do not depend on the selection.
* You need to enable 'print' when printing is possible - you can even do that
* in the constructor.
*
* A special case is the configuration slots, not connected to any action directly,
* and having parameters.
*
* [configuration slot]
* @li @p setSaveViewPropertiesLocally( bool ): If @p true, view properties are saved into .directory
* otherwise, they are saved globally.
* @li @p disableScrolling: no scrollbars
