added option to allow zooming around the crosshair instead of the center; can be enabled via options or by holding alt while using the mousewheel

Pcbnew: Workaround to fix a crash when filling zone in Pcbnew nanometers (see Bug #1106451 ). Also happens with one of my boards.
Could be a bug inside boost::polygon. This is a workaround, because one never knows if this kind of bug is fixed.
However it fixes this issue for the 2 boards.

Fix bug in  TestSegmentHit( wxPoint aRefPoint, wxPoint aStart, wxPoint aEnd, int aDist ), when aDist = 0. (fix Bug #1106744 )

Pcbnew: fix a very old bug in DRC, pad to pad drc tests: sometimes a test between a rectangular pad and an oval pad was skipped.
Segment Hit Test: enhanced detection near segment ends (noticeable for instance when clicking on short tracks in Pcbnew.
Remove duplicate code about segment hit test.
remove unused file.

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

Gerbview: Fix a minor but annoying issue in gerbview  config: colors setup is broken when running a testing version after an old gerbview version (due to a bug of this old version which breaks the color config)

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

Still try to find a better fix for Bug #1100876, however I am thinking the bug is not in Kicad:
looks like a buggy version of wxWidgets is used, which sends sometimes an unwanted wxCommandEvent event,
when an event::Check() is called inside a function called by a  wxUpdateUIEvent event.

Pcbnew: fix bug Bug #1101399 (Custom page size gets reset after restarting pcbnew) (bug also in eeschema)
Try to find a better fix for Bug #1100876

It could be a race condition when setting the tools state on and off in PCB_EDIT_FRAME::OnSelectAutoPlaceMode( wxCommandEvent& aEvent ) on some Linux/wxWidgets versions
(does not happen on my computer)

Enhance DIALOG_SHIM to optionally call SetFocus() after the derived class's constructor has been called, for wx 2.8 and wxGTK

Scripting: fix erroneous extension for S exp board files, which prevent to open a .kicad_pcb file from a python script
Make scripting version compilable on platforms where the python executable is not python2:
Just define it by -DPYTHON_EXECUTABLE=<python executable filename> when running cmake (there was already a partial fix for this)

 Make scripting version compilable on platforms where the python executable is not python2 (define it by -DPYTHON_EXECUTABLE=<python executable filename>)

Pcbnew: store in configuration the default line width (now  in mm), under a new keyword, to avoid a strange behavior of pcbnew in decimils version (old pcbnew versions), after running pcbnew in nanometers.

AUTHORS.txt: add some contributor names (I certainly forgot some other contributors, and I apologize).
Demos: convert .brd files to .kicad_pcb files and fix 2 broken files

Kicad manager: fix a recent bug: project tree not updated when kicad is launched by a command line with a project name to open.
Pcbnew: export vrml:
* move dialog functions to a new file: dialog_export_vrml.cpp (to be consistent with other dialogs).
* fix some coding style issues
* added patch from Cirilo Bernardo.

* 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.

3D viewer: allows  import of models created with openscad and convertedvia meshconv to wrl (thanks to Georg Gast <georg@schorsch-tech.de>)
Export VRML: fix scaling issue for pcbnew - nanometers.

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.

Until now, 2 tracks were seen as connected only if one end of the first track is *exactly* on one end of the other track.
Now the 2 ends are seen as connected when they are "near" i.e. the distance between the 2 ends is < track width/2
