Eeschema:  * Preselect the currently chosen component in the browser when pressing the thumbnail view.
* Various smallish documentation updates in the component chooser area.

* Pressing 'Enter' while the focus is in the tree did not work due to the
  double-click wxWidgets workaround.  Make it work.
* More clearly document what is happening and how it can be tested.

Eeschema: Remove usage of tabs in dialog_choose_component.cpp strings, because they do not work very well on Linux, and do not work on Windows.
Fix incorrect rotation of components (CCW instaed of CW)

* Manually change fbp file minor version number so dialog could be edited
  with latest release version of wxFormBuilder.
* Give component view panel more weight for improved component view size.
* Add padding around dialog button sizer.

* Improve component chooser redraw to fit in wxWidgets redraw strategies.
* Use LIB_COMPONENT::Draw and LIB_COMPONENT::GetBoundingBox for drawing the
  component
* Make resize redrawing work properly.

* Allow to select units in components that have more than one right in the
  component chooser dialog.
* Keep chosen unit in history.
* Show preview of current component unit as thumbnail image next to the
  description box.
* Fixes lp:1280567

* make some more fields 'const' that can.
* Instead of previous/next _visible_ element, Go through
      previous and next element. Otherwise the cursor stops moving
      if the item is only partially visible.

Minor change: Eeschema+Pcbnew: display timestamp in edit dialogs (for footprints, sheets, components)

eeschema/dialogs/dialog_lib_new_component.cpp was not expanding part name field nor setting initial focus.

Better GITHUB class header documentation, better eeschema library field dialog stretching and title.

* 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.
