Pcbnew: speedup netlist read, when some footprints are not found, by caching the non-existent footprint names, which are searched only once in libs.
When a non existent footprint is used by many components, this footprint was previoulsy searched in libs for each component, which is very time consumming.

Pcbnew: read netlist enhancements: add option to remove single pads nets, add enforce tests to report non existing netnames in zones.
Fix also some very minor errors in comments.

Pcbnew: add more test when reading a netlist file: verify if all pads found in netlist are found in corresponding footprints (no missing pads).

Pcbnew: Fix a bug when reading a netlist which forces pcbnew to read lib files to find a footprint even if the right footprint is already loaded (which explains the long time to load netlists)
Netlist dialog: add option to report only most important messages. Useful for large boards.
class REPORTER: add features to allow a basic message filtering (flags to report all/warning/error messages)
Fix Bug #1214599 ( tools are deselected on Move command )

Lay basis for a more full featured usage of boost, including compiled libraries such as unit_test_framework, system, etc.  Move headers now into boost_root/include/boost/.

Others: fix very minor issues.

* Fix the last parts of Bug 1204712 by removing DateAndTime from library file and documentation file formats. They weren't being loaded anyway.

- Comment fix

* Use a regular expression to enforce more stringent bus label testing.
* Add validator to edit label dialog to prevent space character from being
  used in labels.

Pl_Editor: fix copyright in files. Enhancement when creating new items.

REMOVE: vias from specctra DSN export which are not in a netclass.  Use only netclass based via sizes in freerouter.
Some of the vias in the class-less list were setting the drill hole size to zero and this made no sense to freerouter.

Replace the wxFilePickedCtrl in Option Page dialog by an usual wxButton + wxTextCtrl, because under wxWdgets 2.8.12 the look and the behavior is very different between Windows and Linux.

dialogs which allow editing of component properties.  The button
is active when the table row cursor is on the DATASHEET field only.
When active, and your datasheet is a URI, then your default
browser will be launced to show that datasheet if it can find it.
This incentivizes use of http:// links for datasheets.

ENHANCE: specctra export Edge.Cuts "endpoint mismatch error message" was not showing exact coordinates with sufficient resolution

Pcbnew: footprint wizard dialogs: minor fixes, and fixes a not working parameters dialog under Windows, due to an incorrect Printf format.
remove scripts/packagesrc.sh, fully outdated (still refers svn repo)  and not commented.

REMOVE: USE_PCBNEW_NANOMETERS by making it the only way to go in pcbnew, effectively removing the deci-mils build.

was simply a pointer to an object on the display list.  At times this object
would disappear from the display list, in the test case because of a concatonation
of two wires, and if you then tried to clone the non-existent object you'd get a 
crash.  This was not merely a bug, but a naive design choice. IMO.
Now the item to repeat is cloned, so will never also be on the display list.

formatting and fix selection clarification bug in pcbnew, could not move reference text when hidden under another footprint

must be defined if that is the build type wanted. This only affects a text string
anyways, is not particularly important other than telling user from which code
branch  the source came.  

2) Change name of "testing" to "product" in that same description within
common/build_version.cpp.  "testing" made it sound frightenly unusable.

Pcbnew: footprint wizard dialogs: minor fixes, and fixes a not working parmeters dialog under Windows, due to an incorrect Printf format.

* Added modified CMake FindPython... modules to support using Python-a-mingw-us distribution when building Windows scripting support using MinGW

fix interface mapping slip-up in wxPoint EDA_DRAW_FRAME::GetCrossHairPosition( bool aInvertY ) const

Save grid origin in .kicad_pcb files only if not 0,0 (to keep compatibility with previous versions of pcbnew, mainly the stable version)
Very minor other fixes (set modify flag when grid origin is moved from the dialog grid)
