standard layer name support from BOARD::GetLayerName().  This function evolved
in a contorted direction over time, and was being asked to return one of 3
different kinds of layer names, even though it only took a boolean to control
that choice.  

Users are better served by forcing them to get to know the concise new 
English Standard layer names.  This is because these concise names show up
in the "pretty" footprint/module files as the standard representation of
both feature and copper layers.

Change the name of BOARD::GetDefaultLayerName() to GetStandardLayerName().
Drop boolean argument to both BOARD::GetStandardLayerName() and 
BOARD::GetLayerName().

* Complete encapsulation of the MODULE class.
* Complete encapsulation of the EDA_TEXT class.
* Encapsulate most of the ZONE_CONTAINER class.
* Add pcbcommon library as a dependency for reSWIGging the scripting
  support.  This should cover most dependency cases.

* Encapsulate most of the MODULE class.
* Start encapsulating the DIMENSION class.
* Lay some groundwork for EDA_TEXT encapsulation.
* Move cleverly hidden MODULE functions into class_module.cpp.
* Use std::swap to exchange TEXTE_PCB values for undo/redo.
* Remove unused members from MODULE class.
* The usual coding policy and documentation fixes.

Pcbnew: fix Bug #1148785 (pcbnew crashes when using only one layer in autorouter ) , and a minor bug in dialog cleanup.

Still fix minor issues in dialog_edit_module_for_BoardEditor.cpp (noticeable only for non English users)

* Fix spacing and consistency issues and debug warning due to improper flex
  grid sizer in module editor module properties dialog.
* Fix spacing and consistency issues in Pcbnew module properties dialog.
* Fix spelling error in DRC dialog message box text.

* Make Pcbnew net list dialog honor escape key on Linux.
* Make Pcbnew swap layers dialog honor escape key on Linux.
* Layout and UI policy fixes for Pcbnew swap layer and net list dialogs.
* Layout and UI policy fixes for Eeschema plot dialog.
* Rename fpip.h to fpid.h.
* Fix FPID class compiler errors.
* Restore fpid.cpp to Pcbnew static library source list.

wxID_CANCEL, 5 pixel border around sizers, resizable search combobox, dialog_shim usage on a few dialogs

Pcbnew: plot Dialog: add a popup menu (try mouse right click in plot dialog) to selected/unselect groups of layers to plot.
All: For new zoom centering option: use Shift+Ctrl key instead of Alt key to select the new zoom centering, because Alt key has a special function under Windows.
2 very minor other changes.

* Fixed spacing issue in pad properties dialog.
* Remove wxSHAPED flag from pad drawing panel to prevent assertion in
  wxSizer.
* Used sane default pad size and drill size settings to prevent wxRound
  assertions.
* Add license to class_board_design_settings.cpp.

added option to allow zooming around the crosshair instead of the center; can be enabled via options or by holding alt while using the mousewheel

Changes for CvPcb to eeschema stuff file: the stuff file generation from CvPcb is removed. Eeschema now imports footprints names from the .cmp usual file created by CvPcb or by Pcbnew (Why to use 2 file formats for the same thing?) .
Pcbnew: in netlist dialog: The user now can choose between the netlist and the .cmp file to import footprints names.
Therfore no need to delete the .cmp file when exists to use only the netlist.
This is useful for users who use CvPcb only once to fill footprints fields in schematic, and after edit/modify the footprints fields in schematic outside CvPcb.

Pcbnew: fix bug Bug #1101399 (Custom page size gets reset after restarting pcbnew) (bug also in eeschema)
Try to find a better fix for Bug #1100876

Kicad manager: fix a recent bug: project tree not updated when kicad is launched by a command line with a project name to open.
pcbnew: export vrml:
* move dialog functions in a new file: dialog_export_vrml.cpp.
* fix coding style issues
* patch add from cirilo Bernardo.

* Improve MSG_PANEL_ITEM to handle message panel information.
* Create containers for passing message panel items between objects and
  the message panel.
* Rename EDA_ITEM::DisplayInfo to EDA_ITEM::GetMsgPanelInfo.
* Remove all direct manipulation of EDA_DRAW_FRAME from all objects derived
  from EDA_ITEM.

Pcbnew: Fix unwanted selection clarification popmenu in board editor after double clicking on a DRC Unconnected error
 (For DRC clearance error, it was fixed  in bzr 3838, but forgotten for DRC Unconnected error)
