* 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.
* 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: in netlist dialog: The user now can choose between the netlist and the .cmp file to import footprints names.
Therfore no need to delete the .cmp file when exists to use only the netlist.
This is useful for users who use CvPcb only once to fill footprints fields in schematic, and after edit/modify the footprints fields in schematic outside CvPcb.
