Plot files : fix Bug #1188664  (full filename instead of short file name, and swapping between sheet path and file name)

* Add option to MODULE::GetPadCount() to exclude non-plated through holes.

page layout: if the environment variable KICAD_WKSFILE points a S expr page layout descr, this descr is used instead of internal descr. Mainly for testing purposes.
Eeschema, dialog edit component: minor enhancement (the last selected notebook page is remembered during a session)

Eeschema, dialog netlist: fix a bug when removing a plugin panel, when is is not the last.
dialog netlist:Add a predefined command string for python scripts, when creating a new netlist plugin entry.

All: use a S expression to describe the page layout (title block and grid references). Work in progress.
This should  allow users to define their own page layout.

which was creating silly strings like 

  PcbTextThickness="    0.300000"

in kicad.pro files.

*) Enhancements to make_lexer().
*) Support multi-threaded build.
*) Switch to "bzr patch" from patch.exe for Windows users.

factor out isNumber() in dsnlexer.cpp, add support for numbers with exponents, leave commented out for further testing

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.

* 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.

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.

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.

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

* Add code for loading, modifying, and saving the global and project
  footprint library tables.
* Add code to load MODULE objects using the footprint library table to
  the footprint viewer.
* Add static methods to FP_LIB_TABLE to support loading footprint library
  tables.

Code cleaning and move worksheet code specific to title block and frame references shape in title_block_shapes.h and title_block_shapes_gost.h
