(svn r9846) -Codechange: introduced ZOOM_LVL_MIN and ZOOM_LVL_MAX for the obvious reasons

Browse Source 
-Codechange: introduced ZOOM_LVL_DETAIL to show/remove details
-Codechange: changed << and >> operator with ZoomLevel to a simple wrapper (that in theory also allows zoom-in besides the current zoom-out)
-Fix r9845: missed some int -> ZoomLevel
