Fixed an issue (footprint name not read from netlist) when using a netlist without the corresponding .cmp file.

Revert to previous dialog_layer_setup_base, and added (conditional compilation) option to hide/show no used inner copper layers and define inner layers order (see changelog) in dialog layer setup.

Fixed bugs 2965646 (Canceling text operation hides text) and 2959930 (Pcbnew inconsistent Layer names sequence)

Updated denis dupeyron email address

Pad edit dialog uses now default layers names in modedit and the current board layers names in board editor

(non consistent edit pin per pin option and erroneous pin number edition)
Pcbnew: fixing a problem in dialog design rules for small screens (768 pixels height); Better look on bigger screens

* For an obscure reason the focus is lost after loading a board file when starting Pcbnew
* (i.e. only when launching Pcbnew from Kicad or from a command line, with a board filename to load))
* (seems due to the recreation of the layer manager after loading the file)
* This is more a workaround than a fix.

* Make USE_WX_ZOOM clipping routine actually clip rather than just test
  if line needs drawn.
* Clean up as many USE_WX_ZOOM #ifdefs as possible.
* Minor coordinate rounding improvements.
* Minor scrolling and panning improvements.
* Remove unused KicadGraphicContext object code.

pcbnew: fixed crash when opening the pad edit dialog from Preference (without current pad to edit) and closing the dialog.

All: added in popup menus hotkeys info for zoom commands

Fixed a size problem for wxSliders used in footprint properties editor (wxSlider very small and not usable). Linux specific.

Fixing vertical size of the design rules dialog to meet our minimal screen size requirement (768 pixels height)

* Fixed clipping bug when USE_WX_ZOOM is enabled that causes rats nest
  to be drawn incorrectly.
* Fix ambiguous function error in trigo.cpp when building with MSVS.
* Add instructions for building wxWidgets with graphics context
  enabled (GDI+) using MinGW/MSYS to COMPILING.txt.
* Initial EESchema find dialog work.
* Set modified flag when using PCBNew global deletion dialog to prevent
  closing without warning user of changes.

* Implement code to allow wxDC to handle coordinate conversions between
  device and drawing units.
* Add build settings to enable wxGCDC for wxGraphicsContext testing.
* Remove wxAUI conditional build cruft as it is now required to build
  Kicad.
* Fix scroll increment size regression to prevent jumping around the
  zoom center position.
* Add find GDI+ cmake module for building on WXMSW when wxGraphicsContext
  is enabled.

Added sample gerber files for test (gerbview has problem with 2 files)
