class PLOTTER: dash lines parameters in one place for plot. I made minor changes (values in mm and set to give the same size as dashed lines drawn by wxDC, using short dash.)

Fix a few minor coverity warnings.

Eeschema now uses dashed lines for graphic lines (to be consistent with plot functions and toolbal icon).
Fix an old bug in some envionments which warp the mouse on a bad monitor when opening eeschema, pcbnew and some other windows, only noticeable guys who are lucky enough to have more than one monitor.

 - CACHED_CONTAINER::GetVertices: removed useless and unused function
   which does nothing but tainted the API
 - SHAPE_LINE_CHAIN::Collide( const BOX2I& aBox, int aClearance ):
   removed an outdated function with assert(false)
 - SHAPE::BBox(): fix a small typo in the doc string

Minot fixes: Minor coding style issues fix (tab -> spaces). Add missing GetClass to all classes derived from EDA_ITEM. Make debug method Show() only compiled in debug mode.

Footprint editor: set the default footprint text size to 1 mm. Minor cleaning code. Very minor other fixes.

* Fix default KISYSMOD/KISYS3DMOD (#ifdef typo) for OSX builds.
* Remove setting KIGITHUB from kicad/pcbnew Info.plist in favor of hardcoded default
  setting for OSX builds.
* Remove now unneeded Set3DShapesDefaultPath() and other small things.

Fix some coverity warnings (not initialized members). Add comments. Better (more informative) title in dialog to download .pretty libs.

* move not shared files (sch_item_struct.*, sch_base_frame.h) to eeschema;
* move wxEeschemaStruct.h to eeschema and rename it schframe.h to be consistent with the other corresponding file name schframe.cpp;
* remove few not needed  #include

* Fix unitialized variable in MSG_PANEL_ITEM default ctor.
* Fix a bunch of uncaught exception issues.
* Fix a memory leak in the NETLIST_READER::GetNetlistReader() when an
  an attempt to read an invalid net list file occurs.

Now OpenGL can report its problems instead of shutting down the application.

Rename eeschema/dialogs/dialog_sch_find.fbp to dialog_schematic_find_base.fbp, to be consistent with other dialogs. 
Pcbnew run from the project manager: add menu Save Copy As..., which is the same command as Save As ... in stand alone mode, but with the constraints of a project (no cwd change, no board filename change, and keep project settings)

Extend arrays and duplicate to pcbnew (GAL and legacy), covering modules, text, lines, tracks, dimensions and targets.

Text arrays can now use "%s" as a placeholder to be substituted with the array index.

Also expand menu options for move exact, arrays and duplicate.

Minor fixes for arrays - use proper unit parsing, add numbering start for circular arrays

Add circle radius indicator to array dialogue
