added the example gen_gerber_and_drill_files_board.py in demos, which shows how to do that.
Fix a Printf format issue (shown in Debug mode) in Libedit (%d used for a size_t, changed in %zu)

Minor fixes: dialog rescue: make strings translatable. Remove a few coverity warnings (not initialized members). Very minor other changes.

Add a python script example in demo folder to create various plot files from a board. Fix also some issues in plot controller helper class.
Important note: from a python script one cannot plot the palge layout, because the page layout template file is not stored in the board file, but it is part of the project.
Because when using a python script, the project is not loaded, the page layout template is not known.
Trying to plot it crashes the script.

Minor fixes in dialog rescue: missing title, incorrect refresh due to use of a wxPaintDC outside a paint event, and coverity warnings (not initialized members).

Eeschema: add missing rotate and mirror sheet in sheet context menu (these transforms were possible in block commands, but  not from the sheet menu).
Fix a i18n issue in field names when loading a component, if the language was changed during a session, and kicad not restarted (see Bug #1448654).
However changing the language needs restarting kicad, in order to have all messages or menus translated.

* Add code to test if any of the components in the schematic cache have been changed
  in the component libraries.
* Prompt user to accept or reject components when changes are found.
* If the user chooses to use the components in the cache, create a new library with the old
  components and add it to the beginning of the component library list so the schematic will
  not be changed.
* Create dialogs to handle user feedback and status.

* Use "Close" in the file menu of every main frame window instead of the
  mismatch of the terms "Close", "Exit", and "Quit".
* Change the terminology in the Pcbnew graphic text edit dialog to match the
  module text edit dialog.
* Improve the layout of the Pcbnew graphic text dialog.
* Fix some wxPrintf parameter type assertions for 64 bit time_t.
* Fix all (at least I think I got all of them) duplicate menu accelerator
  characters.

Minor fixes: dialog_create_array.*  files:  clean code ( remove useless declarations and functions ). 
fix a few coverity warnings about not initialized members in ctors.

Use whatever comes from the lib_path in the fp-lib-table, thus opening up the same plugin for alternative generic servers.

Now these parameters are stored in user config, not project config ( they are not really related to a given project, they are just a setup during an edition),
and the schematic editor and the component editor have now separate parameters, because they are separate editors with different constraints.
component editor: repeat pin enhancement (from and idea of Edward Johns)

footprint wizard python plugins management: Fix a memory leak. Remove useless and outdated code, and add a minor enhancement.
Make a string translatable in a pcbnew info dialog.

ModEdit: fix a  refresh issue after deleting a pad (depending on the position of the pad, the pad was sometimes not immediately undrawn).
Fix a few coverity wanings (not initialized members in ctors)

Very minor coding style issue fix in hotkey code (pl_editor and gerbview).
Fix a compil error  using c++11 option for painstaking compilers

Dialog layers setup: cosmetic enhancements (fix a very minor issue on Windows). Remove a not used and outdated file.

Hide "Power component value text cannot be modified" in libedit (which should  be displayed only in schematic editor for power parts)

Better handling of disabled layers when editing a footprint (value, ref) from the board editor (avoid the "illegal layer" message box when possible).

Previously, only the lib named "power" was used (and therefore power parts defined in other libs not shown).
Now, all power parts can be loaded from any library.
Also, when loading power parts from the chose component dialog or the lib viewer, libs and parts are filtered:  only power parts and libs containing power parts are listed.
Hotkeys: move a few global strings in the files where ther are actually used (and make them local.) and code cleaning.
Fix a few other minor issues.

Removing trailing spaces in some files.

Fix some issues in filling zones normals.
Fix an issue with some models that have materials but didn't defined the diffuse color.
Workaround for Bug #1443431.
Implement some missing "code logic" for pervertexperface normals.
Remove some not used functions.
Calculate normals using double type.

3D viewer: minor fixes. Use our class REPORTER to show warning messages and activity info when building the 3D board view. Add a few comments in sources.
Very minor other fixes.

3D viewer: fix (the fix is not perfect) a minor issue in zone rendering: copper thickness was not good when the option 'Show Holes in Zones" was OFF, and "Show Copper Thickness" ON.
Fix a few coverity minor warnings.
