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.

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)

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.
