This seems to me like the defacto standard for this menu command.
* Added a default filename for save as. Currently it's set to
  "Unnamed file" using _() so its translatable.
* Changed the save dialog in PCBnew to use the path of the "original"
  file as a base for the new file.

* Fix both legacy and s-expression netlist readers when footprints are
  assigned in the netlist.
* Add some helper functions to NETLIST for detecting when footprints are set
  or not set and when they have been changed while loading the .cmp file.
* Rename a few functions to improve their readability.

In most case the assignment to null was not necessary since it was easily provable that the (local) variable wouldn't have referenced after that anyway.

Pcbbnew: fix bug Bug #1172892  (bad drill map file names, when a point is used inside a board file name)

* Tweak the NETLIST_READER code to allow for component footprint names that
  are not found in any library to generate a warning instead of an error and
  update the board accordingly.
* Don't display undo warning in netlist dialog when dry run option selected.
* Rename netlist_reader_common.cpp to netlist_reader.cpp
* Rename netlist_reader_firstformat.cpp to legacy_netlist_reader.cpp
* Rename netlist_reader_kicad.cpp to kicad_netlist_reader.cpp
* Remove cvpcb/read_write_cmpfile.cpp and move the single function it
  contained into cvframe.cpp
* Remove cvpcb/loadcmp.cpp and move the single function it contained into
  class_DisplayFootprintsFrame.cpp.
* Remove cvpcb/readschematicnetlist.cpp and move the single function it
  contained into cvframe.cpp.
* Remove cvpcb/setvisu.cpp and move the few functions it contained into
  the appropriate source file.

* Create separate NETLIST object to hold contents of netlist files.
* Read entire netlist and footprint link files before making applying
  changes to board.
* Add BOARD::ReplaceNetlist() function to eliminate the calls between the
  NETLIST_READER, PCB_EDIT_FRAME, and BOARD objects.
* Change placement of new components below the center of the current board
  or in the center of the page if the BOARD is empty.
* Add dry run option to netlist dialog to print changes to message control
  without making changes.
* Add button to netlist dialog to allow saving contents of message control
  to a file.
* Eliminate the need to compile netlist_reader_*.cpp in both CvPcb and Pcbnew.
* Add netlist_reader_*.cpp to the pcbcommon library.
* Remove redundant load component link file code from CvPcb.
* Modify CvPcb new to work with the new NETLIST_READER object.
* Add compare() function and < and == operators to FPID object.
* Add REPORTER class to hide an underlying string writing implementation for
  use in low level objects.  Thank you Dick for the idea.
* Lots of minor coding policy, Doxygen comment, and missing license fixes.

Pcbnew: fix bug in pcb_parser: incorrect pad local solder paste margin ratio value read when not 0. ( This also fixes bug 1170535 )

The internal BOM generator has bugs. I designed an XSL script, which converts the generated XML Partlist into
a CSV file for Libre Office or Open Office.  It is very easy to use. You can specify it as a plugin for 
Eeshema netlist generator.

It searches for all field names, generates the table headings accounting for all fields found in any part.
Then stuffs all the parts rows according to proper fields.

Eeschema: fix bug #1168116. Netlist generation: remove  dead code and fully outdated option pspice "use net number"
Pcbnew: layer manager: display tooltips using translated form (where internationalized, but always shown in English).

Changed format specifiers of some printf involved with size_t values to %zu to avoid runtime assertions.

Depending on build options seems that wx uses different types for size() so the Format string was not always correct. Put a fat warning in a comment too.

use lower case library names in *.pro & *.sch files, to match actual filenames in the template file set. Noticed on linux.

Also removed EDA_DRAW_FRAME::OnGrid which was totally dead (empty and unused)

Pcbnew: load footprint from modview: Because modview allows user to choose the footprint library, the selected library is forced when the footprint is loaded.
I am not sure this is 100% better, but this new behavior has some advantages, mainly in the footprint editor (you can load a footprint outside the selected library)

pcb_calculator: fix bug Bug #1167345

Slightly retuned for compensating the new position.
