Renamed BOARD_CONNECTED_ITEM::SetNet() -> SetNetCode()
Added BOARD_CONNECTED_ITEM::GetNet() for accessing NETINFO_ITEM* of a given item.
Fixed module editor crash when launched to edit a module from a PCB.
Replaced some BOARD::FindNet( item->GetNet() ) calls with BOARD_CONNECTED_ITEM::GetNet().

* Manually change fbp file minor version number so dialog could be edited
  with latest release version of wxFormBuilder.
* Give component view panel more weight for improved component view size.
* Add padding around dialog button sizer.

* Improve component chooser redraw to fit in wxWidgets redraw strategies.
* Use LIB_COMPONENT::Draw and LIB_COMPONENT::GetBoundingBox for drawing the
  component
* Make resize redrawing work properly.

* Allow to select units in components that have more than one right in the
  component chooser dialog.
* Keep chosen unit in history.
* Show preview of current component unit as thumbnail image next to the
  description box.
* Fixes lp:1280567

Fix minor bug in eeschema (opening a relative path does not work) (patch from HennerZeller).

* make some more fields 'const' that can.
* Instead of previous/next _visible_ element, Go through
      previous and next element. Otherwise the cursor stops moving
      if the item is only partially visible.

Fix a minor error in class D_PAD: void D_PAD::Flip( int Y ) changed to virtual void D_PAD::Flip( const wxPoint& aCentre ) (as defined in BOARD_ITEM)
Scripting: fix compatibility current pcbnew version in 2 examples and the default extension of board files  in board.i (was .kicad_brd, now is .kicad_pcb)

Fixed case for the footprint legacy plugin when added module's do not have set parent (BOARD).
Added copyright notice for pcbnew/class_netinfolist.cpp (feel free to correct, it is just copied from corresponding header file).

gr_basic.cpp: rewrite the function which draws the outlines of a thick segment.

* Apply Henner Zeller's patch to add connecting line from reference and labels to component position whilst moving to help identify which component the reference or label belongs too

  Factored out the next-pad-number function

Use environment KISYS3DMOD to know the default path for 3D shapes in footprint editors dialogs, and build short 3D file names.
This value is now shown in these dialogs.
