S60 native looking dialog support.

Related to QTSSIXTY-63 "Make Qt dialogs look native"
S60 dialog support:
* Positioning according S60 rules:
  - in portrait dialogs at the bottom of the screen,
  - in landscape positioned in the center of the screen [unless device supports bottom softkeys], so that softkeys are not covered by the dialog
* If dialog shows extension, then dialog is re-positioned
* Dialog size:
  - in portrait screen wide dialog, height can change
  - in landscape width is the same size as width in portrait (some dialogs are maximized)
* No push buttons or DialogButtonBoxes in internal qt dialogs
(QWizard, QInputDialog, QFileDialog, QFontDialog, QColorDialog, QProgressDialog, QErrorMessage, QMessageBox), instead signals are remapped to softkeys.
* Globally, dialogbuttonboxes are converted automatically to softkeys.

OPEN:
* Needs to be re-factored slightly after softkey API refactoring is finished.

BUGS:
QWizard layout switch is wonky - dialog is not re-sized correctly.
QFontDialog will not fit into device screen (too much widgets in it). Some effort needed to be make it smaller.
Cannot set one softkey at the time softkeys => Options menu and right softkey cannot be set separately [SoftKey re-factoring will help]
Dialogs cannot get touch events to softkeys [SoftKey re-factoring will help]
