3D viewer: allows  import of models created with openscad and convertedvia meshconv to wrl (thanks to Georg Gast <georg@schorsch-tech.de>)
Export VRML: fix scaling issue for pcbnew - nanometers.

EDA_LIST_DIALOG: add a filter option to select names to display is list, from a  kamil zorychta's patch <kamil.zorychta@gmail.com>
Use wxFormBuilder to create EDA_LIST_DIALOG_BASE, like other dialogs.
Minor code cleanup (remove unused functions and coding style fixes) and minor bug fixes.

Until now, 2 tracks were seen as connected only if one end of the first track is *exactly* on one end of the other track.
Now the 2 ends are seen as connected when they are "near" i.e. the distance between the 2 ends is < track width/2

Pcbnew: Fix unwanted selection clarification popmenu in board editor after double clicking on a DRC Unconnected error
 (For DRC clearance error, it was fixed  in bzr 3838, but forgotten for DRC Unconnected error)

Eeschema:commit patch <Prevent Eeschema from opening the same file twice> with a small fix for windows.

2) Add PCAD_PLUGIN to _pcbnew.so for scripting, fixing a linking bug.

Fixes a bug in the template file copying mechanism. The previous code failed to honour sub-directorys and flattened the whole tree whilst copying files.
I have fixed this so that sub-directories that are not the meta directory will get copied verbatim into the new project directory.

* Use the recent wxFileSystemWatcher to automatically update the tree project when a file is created/deleted/renamed in the project directory
(and if the file type is usually shown by the manager.)
Needs wxWidgets 2.9.4 or more recent.
* Also code cleanup, dead code or useless code removed.

Kicad manager: first use of wxFileSystemWatcher (only with wxWidgets >= 2.9.2) to monitor files list.

Pcbnew: Add pcad2kicad pcb plugin, to import PCAD boards ( .pcb ASCII data file PCad 2000 format ) from Alexander Lunef

* Create new GEDA PCB plug in.
* Add support for opening GEDA PCB footprints with module editor.
* Make import footprint file dialog remember last selected footprint
  type during current session.
* Update module editor file import to use new GEDA PCB plug in.
* Let IO_MGR know about GEDA PCB plug in.
* Create a WHITESPACE_FILTER_READER to simplify parsing GEDA PCB footprint
  files.

Pcbnew: board editor: allows pad edition by hotkey 'E' (was accessible only by mouse button right click)
All: minor code cleaning and very minor bug fixes.
