Items are not recached until GAL is changed (earlier it was done on every rendering backend switch).

* 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.

pcb_parser failed on (fill yes (arc_segments 16) (thermal_gap 1.99898) (thermal_bridge_width 1.99898))

Removed BeginLayer and EndLayer functions. Resolved Cairo layers drawing problem in a different way.

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

Tidied up event handlers.

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.
