* fix incorrect bounding box size calculation of schematic components.
* fix incorrect bounding box position and size used when schematic components are not found in lib (dummy lib componen used).
Pcbnew:
* Fix issues in block selection for arcs in modedit. Minor code cleaning.
CopyToClipboard: fix incorrect call to PrintPage (bad parameters)

kicad: fix Russian GOST page reference sheet - add field 24-25

Change board bounding box calculation to include all board items by default in pcbnew. Add a parameter to look for board edges only.

* Merge two duplicate case statement and delete pin code paths into a
  single delete function.
* Make all delete commands use new delete function.
* Fix a few set tool ID calls to use default cursor instead of arrow
  cursor.

* Make EDA_DRAW_FRAME current tool ID member variable private.
* Added global no tool selected ID to replace application specific no
  tool selected IDs.
* Change SetToolID to prevent setting the tool ID to anything less than
  the new global no tool selected ID and assert on debug builds.
* Change command and update user interface command event handlers to use
  new global no tool selected ID.
* Fixed schematic library editor add pin hot key handler.

Fix other issues.

Cvpcb: code cleaning.

* Remove global key press variable.  The key press is know passed to
  GeneralControl().
* Removed unused old mouse buttons global variable.

* Fixed ambiguous call to sqrt() MSVC compiler error.
* Fixed a bunch of type conversion warnings in GCC 3 (MinGW).

* CVPcb now uses wxUpdateUIEvent instead of set toolbars.
* Removed duplicate event handlers in CVPcb that were factored into
  EDA_DRAW_FRAME.
* Fix definition of GeneralControle() in CVPcb that prevented it from being
  called.
* Remove rarely used and scary refresh code GeneralControle() method in all
  main frame windows.
* Factor zoom menu and tool bar command IDs down to EDA_DRAW_FRAME.

* Old control state handling code completely removed in all applications.
* Factor common control state handlers into EDA_DRAW_FRAME.
* Replaced EDA_ITEM test for newness with IsNew() method.
* Factor vertical right toolbar command handlers out of giant edit command
  switch statement in EESchema and PCBNew.

1- incorrect mouse cursor position when clicking on an ERC error message from dialog ERC window to go to the corresponding marker.
2- broken behavior of hierarchy navigator (horizontal toolbar, hierarchy tool)

Tune pcbnew plot dialog. Make actual plotting code independent of dialog widgets and get settings from PCB_PLOT_PARAMS instead.
