(useful for boards having more than 2 layers)
Eeschema:fix compatibility with old schematic files, when they contain ERC markers.
Pcbnew: better test for allowed layers when creating/editing Dimensions and some other Graphic items
Drc: fix comments and messages for some drc tests.
Fix minor bugs in cleanup dialog options and plot solder mask function (thanks to Lorenzo to locate these bugs)
Moved switching canvas routines to pcbnew, as they are used only there right now (otherwise libgal would have to be linked to every Kicad application).
Because now there are 2 formats, board backup files extensions are .brd-bak or .kicad_pcb-bak instead of the old .000 extension, depending on the initial file format.
* Add footprint methods to PCB_IO.
* Add FP_CACHE and FP_CACHE_ITEM for handling new footprint library design.
* Add code to save legacy libraries in new format.
* Change behavior of BOARD_ITEM::GetLayerName() to return the default layer
name when the item does not have a BOARD as a parent.
* Minor changes to the module output formatter when writing to module library
files (no BOARD as parent).
* Add new (and some that I forgot along the way) CMake flags to
EDA_BASE_FRAME::CopyVersionInfoToClipboard().
* Add -Wno-narrowing to GCC flags to stop GCC 4.7 from complaining about
a conversion from int to unsigned in the Boost polygon library.
* Add INPUT_STREAM_READER to richio.cpp to allow using any object derived
from wxInputStream as a LINE_READER (needs to be validated).
This is *a work in progress*, so some features are missing, and/or could be modified.
Mainly keepout zones are not yet exported to autorouters, and pads are not taken in account.
Some code cleanup in polygon.*
* Correct all user strings and comments for the correct capitalization of
application names according to JP. They are KiCad, Pcbnew, CvPcb,
Eeschema, and GerbView.
* Add a note the the user interface policy about the correct capitalization.
* Make EDA_DRAW_FRAME current tool ID member variable private.
* Added global no tool selected ID to replace application specific no
tool selected IDs.
* Change SetToolID to prevent setting the tool ID to anything less than
the new global no tool selected ID and assert on debug builds.
* Change command and update user interface command event handlers to use
new global no tool selected ID.
* Fixed schematic library editor add pin hot key handler.
* Old control state handling code completely removed in all applications.
* Factor common control state handlers into EDA_DRAW_FRAME.
* Replaced EDA_ITEM test for newness with IsNew() method.
* Factor vertical right toolbar command handlers out of giant edit command
switch statement in EESchema and PCBNew.
