keybind_item.patch

Proposed patch add the "key" property to the menu item definition that allow to define the hotkey for item action without copypast the action to the rc.xml.
Exampe:

menu.xml
    <item label="Terminal" key="W-t">
      <action name="Execute">
        <execute>urxvt</execute>
      </action>
    </item>

This is equivalent of

menu.xml
    <item label="Terminal">
      <action name="Execute">
        <execute>urxvt</execute>
      </action>
    </item>

rc.xml
    <keybind key="W-t">
      <action name="Execute">
        <execute>urxvt</execute>
      </action>
    </item>
