Moved fields containing information about currently used color, shader and transformation for vertices from VBO_ITEM to VBO_CONTAINER (OPENGL_GAL).

Added VBO_CONTAINER as a faster storage for vertices (OPENGL_GAL), tuned for exchanging data with GPU.

Removed a few unnecessary variables and fields from OPENGL_GAL.
Added function GAL::ClearCache() for freeing memory used by cached items.
Fixed a few memory leaks (tesselator, PAINTER's settings & VIEW_ITEM's groups).
Changed a few functions into inlines.

Removed indices storing from VBO_ITEM as they are always consecutive numbers. Removed storing pointers to VBO_ITEMs that have to be drawn - instead they are memcpied to mapped GPU memory.
Some functions of VBO_ITEM became inline.

which was creating silly strings like 

  PcbTextThickness="    0.300000"

in kicad.pro files.

Switching to OpenGL using shaders backend on the fly (changed keyboard shortcuts: different backends are available using Alt+F9..F12).

Shader's parameters are stored in VBO_ITEM. Changed VBO_ITEM data structure. Added UseShader() function for selecting shader for a given VBO_ITEM.
Added one main vertex & fragment shader program to be used for with all kinds of items (type of shader is selected using attributes that are stored in VBO). Currently available shaders are: at-least-1px-width line, filled circle and stroked circle.
Removed unnecessary param (aDepthOffset) from a few functions (OPENGL_GAL::drawSemiCircle(), OPENGL_GAL::drawLineCap()). Removed function OPENGL_GAL::DrawRoundedSegment(). Changed some asserts to debug info or error log.

Display linking errors in debug mode for shaders. Added SHADER::GetAttribute() function for getting shaders attribute location.

Pcbnew: Fix Bug #1185556. fix issue about Solder Paste Ratio value which was accepting only one digit in mantissa in 3  dialogs  (now 6 digits in all dialogs).
fix potential issue in .kicad_pcb file creation, in some places where a %g or %.16g format was used:
al least under Mingw/gcc4.7.2, the floating number was written using scientific notation, not accepted by the S-expr reader.

Kicad template selector dialog: add an info line showing the template path in use. Fix very minor bug #1185462

* Add footprint library table loading to footprint editor.
* Overload FOOTPRINT_INFO::ReadFootprintFiles() to read footprints from the
  footprint library tables.
* Fix a bug in FP_LIB_TABLE::IsEmpty() when the table has a fallback table.
* Add code to FOOTPRINT_EDIT_FRAME to use footprint library tables.
* Add an optional build time version of PCB_EDIT_FRAME::loadFootprints() to
  populate netlist footprints from footprint library table.
* Remove adding footprints to board whenever GetModuleLibrary() is called and
  move loading locally as required.
* Add missing source file license comments and coding policy fixes.

because under Linux and wxWidgets 2.9, wxStaticBoxSizer are very ugly (text not readable in this dialog)
(Does not happen with wxWidgets 2.8)
Eeschema hotkeys: remove duplicate keys in key editor.

and fix a minor issue in netlist dialog.

Fix minor issues in print/plot: filename not printed, sheetname incorrect in eeschema

   File "rules" has instructional text as comments near top.

2) Convert all text files in repo to LF line ending form.
   Any checkout done with "rules" in play will convert the working
   tree to native line ending, while keeping repo as LF line ending.

very minor other chnages.

Cvpcb fix bug  #1183796 and fix bug when a fp lib is not found : the name of the missing file was not displayed in message window.

Netlist reader: fix issue when reading an ORCADPCB2 netlist (which fixes also bug 1184023) and fix a Cvpcb crash when trying to read an unknown netlist format.

Pcbnew: fix bug in drag module: connected tracks were not dragged.
worksheet: code cleaning.
