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.

Very minor other fixes.

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.

Eeschema: fix a bug which crashes Eeschema (when a label is being created, and its type is changed  by popup menu, for instance to a text, before it was put on schematic)
remove unused file and minor coding style fix

Eeschema: fix Bug #1102381 <eeschema: -cache.lib file not created the first time you save a schematic>

* 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.

EDA_LIST_DIALOG: add a filter option to select names to display is list, from a  kamil zorychta's patch <kamil.zorychta@gmail.com>
Use wxFormBuilder to create EDA_LIST_DIALOG_BASE, like other dialogs.
Minor code cleanup (remove unused functions and coding style fixes) and minor bug fixes.

Eeschema:commit patch <Prevent Eeschema from opening the same file twice> with a small fix for windows.

Pcbnew: board editor: allows pad edition by hotkey 'E' (was accessible only by mouse button right click)
All: minor code cleaning and very minor bug fixes.

eeschema: make new netlist format (S expr netlist format) the default for Pcbnew netlists in dialog netlist.
Also move netlist_control.* to dialogs/dialog_netlist.*, to be consistent with other file dialogs.

Pcbnew: Drc dialog: fix a old very minor bug.
Added: single click on an item in marker list moves the board  graphic cursor on the corresponding marker location on the board
Double clicking is not modified.

Eeschema: Add hotkey 'U' to edit reference. Better filtering for  hotheys V, F, U: now the corresponding field is selected without selection list between component and the field.

Try to fix an unwanted left mouse release button event, when closing a dialog on a click or double click,
and therefore when the mouse butoon is released in the parent window
Minor other fixes.

window which would cause the part to be parked rather than staying
in drag mode.

Library Browser tool, you have to select it in the components listbox
and then press the "Insert component into schematic" button to close the
window and return to the schematic.

The attached patch enables the selection and insertion of a component in
schematic by double clicking on it in the Library Browser component
listbox. As the double clicking should have effect only if the Library
Browser was launched to load a component in schematic, the patch checks
for NULL the m_Semaphore variable, used two distinguish the mode in
which the Library Browser is running (modal, used when inserting a
component in schematic, or non-modal).

Polyline.cpp: fix a bad wxASSERT test which generate error messages in Debug mode when there is no error, in DEBUG mode, when filling zones with holes.
