This feature cannot work reliably for reasons explained in lp:1463505. Remove
the option on OS X builds and force cursor to the small one.

* The board ratsnest visibility state was being saved in both the board file
and the Pcbnew configuration files causing visibility state issues. Use the
board file to save the board ratsnest visibility state.
* Remove all of the board ratsnest save visibility state to configuration file
code.
* Add code to set the board modified property when layer visibility states
change to give the user a chance to save the state in the board file.
* Some minor code cleaning and coding policy fixes.
* Add code to allow each editing window it's own undo/redo count.
* Add code to allow for infinite undo/redo when count is set to 0.
* Add edit control to all editing windows general options dialog for
user configuration of undo/redo count.
* Add code to save and restore undo/redo count for each editing window.
this option was possible only by modifying the way display options are managed.
before these changes, display options were a global DISPLAY_OPTIONS class instance.
Now each EDA_DRAW_FRAME(and derivated classes) includes its own DISPLAY_OPTIONS class instance.
As a consequence, some duplicate display option variables in these classes have been removed, because there were just duplicate variables of the DISPLAY_OPTIONS class instance.
Refactored code that handled zooming events.
Added PCB_RENDER_SETTINGS::Get/SetSketchMode().
PCBNEW_CONTROL reacts to hot keys changing display modes (sketch via/tracks, high contrast).
Added separate layers for pad netnames (now these are divided into multilayer/top/bottom pads).
More appropriate layers are selecting a copper layer in the high contrast mode (now it shows the copper layer itself, vias & multilayer pads and netnames).
New methods in VIEW class: SetTopLayer(), EnableTopLayer() for managing the top layer display.
New method in PCB_RENDER_SETTINGS class: LoadDisplayOptions() for applying display settings like high-contrast, outline display of items, etc.
* EDA_DRAW_PANEL completely encapsulated.
* Moved OSX m_overlay member from EDA_DRAW_PANEL to EDA_DRAW_FRAME where
it is used.
* Doxygen comment warning fixes.
* EDA_DRAW_FRAME completely encapsulated except for DrawFrame member.
* Moved members specific to Pcbnew from EDA_DRAW_FRAME to PCB_BASE_FRAME
or PCB_EDIT_FRAME as appropriate.
* Replace EDA_TOOLBAR with wxAuiToolBar as EDA_TOOL bar provided no
additional functionality and made code less readable.
* Remove EDA_TOOLBAR class definition from wxstruct.h and delete file
wineda_toolbar.cpp.
* Rename tool bar members to something more descriptive since the
horizontal and vertical references wont mean anything once the
tool bars are movable.
* Lots of dead code removal.
* Factor auto save common code into base frame class so all frame windows
can take advantage of the shiny new auto save goodness.
* Use a timer instead of depending on mouse and keyboard events to trigger
an auto save.
* Check for auto save file when opening a board and ask user if they
wish to use the auto save file or the last saved board file.
* Protect all base frame public members.
