* Replace all occurrences of the word "part" with "unit" when referring to
  multiple unit components for improved consistency.
* Replace "shared by" with "common to" when referring to objects (lines, arcs,
  pins, etc.) that are common to all units.
* Improve wording in library component properties dialog.

* Fix replace bug to handle case sensitivity properly.
* Fix replace bug where the item index was getting updated incorrectly.
* Fix replace infinite loop bug on replace all.
* Make find/replace view update code a separate function.
* Rearrange find/replace trace string to add tracing to EDA_ITEM::Replace().
* Add IsComplexHierarchy method to SCH_SHEET_LIST for future find/replace
  improvements.

Pcbnew: Fix issue when displaying net names and/or pad numbers including the "<" char in drc dialog, because drc dialog uses an wxHtmlWindow to display drc messages, and the "<" char has a special meaning and is not allowed in texts (now replaced by the" &lt;" sequence in messages displayed in html)
Eeschema: replace "<" and ">" by "(" and ")" in autogenerated net names, to avoid other issues in html messages.
Very minor other fixes.

Eeschema: netlist generation: fix bad choice for the "best net name" when selecting a net name between labels connected to the same net.
Code cleanup and remove unused file.

Fix an annoying issue about not named nets:
now, these nets are named from the component references and pin names which are connected.
therefore, unless the net or the footprint references are modified, the net name is not modified between 2 netlist calculations.

* Fix Bug 1219239 - EESCHEMA crashes when editing a template field in libedit through the context menu

* 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.

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.

*) 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.

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.

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.

In most case the assignment to null was not necessary since it was easily provable that the (local) variable wouldn't have referenced after that anyway.

Eeschema: fix bug #1168116. Netlist generation: remove  dead code and fully outdated option pspice "use net number"
Pcbnew: layer manager: display tooltips using translated form (where internationalized, but always shown in English).
