Deskbar: Scale cut-off leaf icon in horizontal mode

Fixes #8505 restoring the aesthetic integrity of the cut-off leaf.

Add vertically & horizontally centered, whole vector icon to rdef.

Reformat BarMenuTitle.h rename header guard from BARMENUTITLEH to
BAR_MENU_TITLE_H.

Created TDeskbarMenuTitle subclass which deals with Deskbar menu
item stuff like getting the icon from vector data and pushing the
leaf down a few pixels to cut off the leaf (maintaining its aesthetic
integrity).

Made TBarMenuTitle methods virtual. Remove unused expando constructor
parameter and private variable.

Add a TODO to scale the bitmap if we can't find any vector icon data.
With non-vector bitmap it behaves same as before this commit in
horizontal mode.

Adjust kMinimumTrayWidth to restore Deskbar's minimum width to its
classic value since days of yore, 143px. This, perhaps not coincidently,
is exactly the amount fit 7 replicant icons. Update constants in the
code to reflect this reality. Adjustable width coming soon.

replace dynamic_cast<TBarApp*>(be_app) with a static_cast in 1 place.
