* 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.

remove "~" from empty *.lib component fields, replace with "", doctor old *.lib fields to blank if that was the intention

Remove duplicate code to draw and to plot title blocks  (more than 1500 duplicate lines). Note: this is a work in progress.
Code cleanup

* 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

Pcbnew: fix bug 1179877, due a bad default  copy constructor, after  my changes about CPOLYGONS_LIST class.
More about CPOLYGONS_LIST work.

Pcbnew: fix minor bug about  plot line width.

* Fix a bug when full file name and path are passed to FOOTPRINT_INFO::
  ReadFootprintFiles() which I created in bug fix lp:593989.
* Fix a wxString debug assertion in EDA_APP::InitEDA_Appl() when the KICAD
  environment variable is defined as an empty string.
* Add error dialog when libraries cannot be found in system search path
  when loading footprint using the select footprint dialog.
* Add footprint library name column to the EDA_LIST_DIALOG when selecting
  footprints from the list.
* Allow reading all columns from the selected row in EDA_LIST_DIALOG.
* Remove redundant sort from EDA_LIST_DIALOG constructor
* Add library name member variable and accessors to FOOTPRINT_INFO.
* Make headers translatable for Eeschema select component from list dialog.
* Add some helper methods to FPID for identifying the FPID type and validity.
* Remove a bunch of trailing whitespace and add missing license comments.

Eechema: fix bug : when saving the schematic project, the lib cache was saved under the current sheet opened, not the root sheet.
Pcbnew: clamp default plot line width between 0.02 and 2 mm. the other bug (saving this parameter in internal units instead of mm is not fixed)

(explanation: float is implicitly promoted to double anyway, it's only useful
for storage; also a fp variable forces conversion of other int in the expression
without needing a cast)
Typo fixes in some comments 'floatting' -> 'floating' :D
