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.

Pcbnew: Export vrml: fix an issue for 3D shapes having a local offset defined: the local offset was not correctly scaled.

the crosshair after zooming.

This method is only used when the ALT key is held while using the mousewheel or
if it's permanently enabled in the options dialog next to the middle mouse
button panning option.

Commit patch from Antia Puentes relative to bug Bug #1125047 : PcbNew: Insert a footprint in the board, from the Library Browser, by double clicking on it, with a change to avoid the button release event (from the double click) to be seen by the main window.

Add CheckCXXSymbolExists.cmake to fix configure bug using CMake versions prior to 2.8.6. (fixes lp:1124854)

add -fPIC for all builds, even cross comiling to Windows from Linux, even non Debug and Release builds

* Add check for pad type and force drill size to zero if pad is surface
  mount in PCB_PARSER.
* Modify the D_PAD SetAttribute method to clear drill size if pad type is
  set to surface mount.

* 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.

Eeschema: All fixed fields are now always saved in libraries. Therefore the footprint field can be set in lib (size, visibility) and imported in schematic with its predefined attributes, even if the footprint text is not set.

* Improve the stable and testing build version option logic.
* Use CMake FindPythonInterp to configure the Python interpreter.
* Use Python interpreter to determine the system Python module install
  path if not already defined on the command line.
* Add header symbol checks for asinh(), acosh(), and atanh().
* Add test source to check for isinf() which can be defined as a C++template.
* Replace conditional compile on windows systems for aXXXh() with CMake
  configuration tests.
* A few minor MSVC compile fixes.
* Fix incorrect python environment string in fixswigimports.py
* Create a separate document for KiCad CMake build options.
* Create a separate how to compile KiCad on Windows document.

eeschema, libedit l fix a bug in lib_arc.cpp which creates incorrect arc start and arc end parameters after rotation or mirror.
the Bug #1121079 is due to this bug, but Bug #1121079 itself cannot be fixed because this is the data inside the lib which is broken.

Pcbnew: Try to find a better workaround for zone fiill bug (crash or bad fil areasl in very rare cases).
pcbnew+Eeschema: Fix a very minor bug: filename not displayed in frame reference.

* Remove ignore mouse events before creating find dialog for true mode-less
  behavior as was originally intended.
