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.

*) add hotkey for setting the grid origin as 'S', in board editor, module editor.
*) re-position the function interface for cursor movement from BASE_SCREEN into
   class EDA_DRAW_FRAME.  This is a prelude to getting rid of BASE_SCREEN or
   splitting it up.

* Force search when wrap past end of list option changes state.
* Fix SCH_FIELD::Matches() for bug in user defined fields which have an ID
  of -1.
* Minor improvements to the find data names to improve source code readability.

Eeschema: fix a *very subtle* bug noticeable only in complex hierachies, for multiple parts per package:
sometimes, the modified flag was set for these components just when switching from a sheet to an other sheet.
Pcbnew: fix Bug #1197414 (dragged track segments does not show clearance area)

Replace in EDA_TEXT::Draw the parameter EDA_DRAW_PANEL* aPanel  by EDA_RECT* aClipBox, which is the actual parameter used by Draw.
This change make more easy to  use this function when a EDA_DRAW_PANEL canvas is not used to draw texts.
Remove dead code in worksheet.cpp.

Pcbnew: netlist dialog: add silent mode option, and tool tip to the 2 options (dry run and silent mode)
dialog_display_info_HTML_base: derived now from dialog_shim.

Rename invoke_a_dialog.h.  Code an alternate implementation for std::string BOARD_ITEM::FormatInternalUnits( int aValue ), for verification.

   and various DIALOG classes called from top frames.  See comments in
   {eeschema,pcbnew}/invoke_a_dialog.h.
*) Move some dialog classes into *.cpp files from *.h files.
*) void SCH_EDIT_FRAME::OnErc( wxCommandEvent& event ) was opening the modeless
   ERC dialog more than once if icon was clicked more than once.
*) Remove BOM stuff.

page layout: if the environment variable KICAD_WKSFILE points a S expr page layout descr, this descr is used instead of internal descr. Mainly for testing purposes.
Eeschema, dialog edit component: minor enhancement (the last selected notebook page is remembered during a session)

Eeschema, dialog netlist: fix a bug when removing a plugin panel, when is is not the last.
dialog netlist:Add a predefined command string for python scripts, when creating a new netlist plugin entry.

fix libeditframe.cpp, which in release build would not show multipart text in listbox.  dialog uses DIALOG_SHIM.

*) Enhancements to make_lexer().
*) Support multi-threaded build.
*) Switch to "bzr patch" from patch.exe for Windows users.

because under Linux and wxWidgets 2.9, wxStaticBoxSizer are very ugly (text not readable in this dialog)
(Does not happen with wxWidgets 2.8)
Eeschema hotkeys: remove duplicate keys in key editor.

Fix minor issues in print/plot: filename not printed, sheetname incorrect in eeschema

   File "rules" has instructional text as comments near top.

2) Convert all text files in repo to LF line ending form.
   Any checkout done with "rules" in play will convert the working
   tree to native line ending, while keeping repo as LF line ending.

very minor other chnages.

remove "~" from empty *.lib component fields, replace with "", doctor old *.lib fields to blank if that was the intention

Code cleaning and move worksheet code specific to title block and frame references shape in title_block_shapes.h and title_block_shapes_gost.h
