QMenu: Sloppy menu selection should allow hovering separators

Setting the current action to 0 clears the sloppy region and
closes the submenu if we hover a separator on the way to the
submenu popup. Now, we choose not to while the sloppy delay
timer is running.

QMenuPrivate: Make sloppyDelayTimer non-static

Keeping the timer static would trigger warnings when enabling
SH_Menu_SloppySubMenus in QCommonStyle in a forthcoming patch.
This would happen if we opened a second level submenu quickly
enough and get the mouse event handler to reset the timer its
parent menu started.

Fix WinRT manifest for Visual Studio.

Visual Studio does not like empty dependencies block in manifest XML.
At least my Visual Studio 2013 fails to open visual manifest editor for
XML containing the following block:

    <Dependencies>
    </Dependencies>

If the block is removed or if the block has one or more PackageDependency
entries the editor accepts it.

Moved the <Dependencies> block to prf, so that it is only written when
project really has dependencies. Also <Capabilities> block is moved to prf
for consistency. On Windows Phone, where the <Capabilities> block is
required, it is kept in the output even if it is empty.
