BOM dialog: remove a not very useful button, and merge its function with an other (not perfect, need more work)
Add message box to show info added in BOM python scripts (See scripts/bom-in-python/README-bom.txt about this info)

Pcbnew, export Solder masks in Gerber Format: fix not working export when the solder mask minimal width is not 0 (the exported shapes were the same as if the vule = 0) with boost version >= 1.56
This is due to the fact the boost::pylygon function resize ( a inflate/deflate function) used for calculations does not work with boost version >= 1.56.
Use Clipper  inflate/deflate function instead. It is faster and works fine.

Modify usage of Inflate/deflate polygon in zone calculations, in order to be compatible with boost::polygon >= 1.56
 Inflate/deflate polygons does not work very well (neither with  boost::polygon >= 1.56 nor with Clipper) for polygons which have holes linked by overlapping segments
(i.e. polygons with holes which can be drawn, because they are see as only one polygon)
Some code cleanup.

Modify usage of Inflate/deflate polygon in zone calculations, in order to be compatible with boost::polygon >= 1.56
Some code cleanup.

* Make defintion of OSX build target a requirement.
* Update OSX build documenation to reflect build changes.
* Update OSX build script to reflect build changes.

Grebview: add info in layer manager for Excellon drill filles, similar to X2 file function info in X2 gerber files.

Eeschema: Netlist generator: remove option to generate the fully outdated old netlist file format (based on a very old Orcad netlist format)
Only the new (S expression) better netlist file format is now used.

Gerbview: Add support for recent File Format Attribute metadata, both for X2 Gerber file format and X1 (R274X) format.
Pcbnew already uses this attribute when creating Gerber files.
Because Gerber files using this attribute identify the board layers stackup, Gerbview (if this attribute is defined) can sort gerber images stach up like the board.
(in layer manager, just right click to access to the sort menu)

Try to fix an issue on Ubuntu/Unity for some dialogs which are not displayed. Adding GetSizer()->Fit( this ) after last dialog "geometry" change (size for instance) or Raise() if the window is not a dialog fix it.
Partial fix. There are few cases where the frame is still not displayed.
Looks like a Unity issue, not a Kicad issue.

Try to fix issues on Ubuntu/Unity for dialogs which are not displayed: adding GetSizer()->Fit( this ) in some other dialogs

Try to fix an issue on Ubuntu/Unity for some dialogs which are not displayed. For most, adding GetSizer()->Fit( this ) in dialog constructor fix the issue, but at least one dialog still is not displayed.

Fix remark 1 in Bug #1393277 (the option "use absolute paths" acts reversed: ticked exports relative paths, unticked exports absolute paths)

* Make title capitalization consistant.
* Replace some instances of module with footprint.
* Use angle instead of orientation where appropriate.
* Remove abbreviations where it made sense.
* Coding policy fixes.

* Make "Drawing" string translatable.
* Add segment length to message panel.
* Add segment angle to message panel.

geometry: IsSolid() and Move() methods, segment overlap detection, some improvements in SHAPE_LINE_CHAIN class.

- fixed walkaround bug causing unwanted overlap/clearance violation when the first segment of trace being laid intersects the obstacle's hull at the same point twice (ie. goes in, turns around and goes out).
- fixed placer bug not splitting the start segment after toggling via placement or changing trace width

- re-worked PNS_LINE_PLACER and PNS_ROUTER classes a bit, removing duplicate class members
- cleaned up Andrew's blind/buried via fixes
- fixed 'custom via width' dialog bug updating the width even when closed/cancelled
- fixed incorrect radius of drawn microvias

Pcbnew: fix Bug #1391561 (PCBNew segfaults on BOM creation).  Does not happen on all platforms. Could be due to use of data just previoulsy deleted.
Very minor other changes.

pcbnew: Modules can be selected with block selection tool without including texts & references (GAL).
