uic3: QToolButton properties usesTextLabel and textPosition need to be converted to toolButtonStyle

in qt3 we use :
<property name="usesTextLabel">
<bool>true</bool>
</property>

and
<property name="textPosition">
<enum>BesideIcon</enum>
</property>

But in Qt4:
it's just one function:
setToolButtonStyle ( Qt::ToolButtonStyle style )
<property name="toolButtonStyle">
<enum>...</enum>
</property>

The uic3 currently does not handle this.

In qt4
there is just 4 enums:
Qt::ToolButtonIconOnly 0 Only display the icon.
Qt::ToolButtonTextOnly 1 Only display the text.
Qt::ToolButtonTextBesideIcon 2 The text appears beside the icon.
Qt::ToolButtonTextUnderIcon 3 The text appears under the icon.
