member variable.
* Add helper methods for accessing the undo item copy member variable.
* Fix undetected bug when changing a text type.
* Added an exchange command to the undo/redo base class for handling undoing
a changed item type which cannot be undone by swapping out the variables.

* Lots of coding policy changes while making the changes above.
* Add item clarification context menu to EESchema when multiple unresolved
items are found at the current cross hair position.

* Add method for returning an item's menu text for menu display purposes.
* Changed EDA_ITEMS container from boost::ptr_vector to std::vector.
* Factor coordinate string conversion code from EDA_DRAW_FRAME to function
CoordinateToString().
* Remove base screen methods from draw frame object and correct current
screen methods in derived objects.
* Move restore old wires function code into schematic screen object.
* Make add junction method use current screen position instead of store
position.
* Move poly line ghosting function into the delete current segment method
as that was the only place is was being used.
* Add method to base schematic object of testing if object has a label
that can be incremented.
* Simplified the schematic hierarchy traversing code.
* PCBNew Doxygen warning fixes.
* Move schematic wire and bus break code into schematic screen object.
* Move schematic test for dangling ends into schematic screen object.
* Remove left over debugging output in schematic screen object.
* Remove unused file eeschema/cleanup.cpp.
* Fix bug in schematic line object hit test algorithm.
* Fix a string concatenation compile error added in r2752.
* Rename class WinEDA_BasicFrame to EDA_BASE_FRAME.
* Rename class WinEDA_DrawFrame to EDA_DRAW_FRAME.
* Rename class WinEDA_DrawPanel to EDA_DRAW_PANEL.
* Encapsulate file name member of base screen object.
* Encapsulate associated screen member of schematic sheet object.
* Create add screen method to schematic sheet object to simplify setting
the associated screen.
* Move the change file name code in the schematic sheet object to the edit
sheet method in the schematic editor frame object to eliminate message
dialogs.
* Improve reference counting in schematic screen object.
* Add helper type definitions for changing schematic object storage to C++
containers.
* Change default build to enable wxDC zooming.
* Move sheet label find function into SCH_SCREEN object.
* Move draw screen items function into SCH_SCREEN object.
* Remove redundant page print method from SCH_EDIT_FRAME.
* Add method to hit test for all items in SCH_SCREEN.
* Add method for testing if junction is required in SCH_SCREEN.
* Fix Doxygen waring in help_common_strings.h
* Move schematic select block from global variable to SCH_EDIT_FRAME.
* Remove redundant schematic drawing code for eeredraw.cpp.
* Move block select code into SCH_SCREEN object.
* Simpilify block item select code.
* Fix bug in SCH_LINE selection state test.
* Add test to schematic objects for connectability.
* Make copy block items function a private method in SCH_EDIT_FRAME.
Rename EDA_Rect::Inside to EDA_Rect::Contains ( EDA_Rect::Inside( const EDA_Rect& aRect ) was very ambiguous )
Fix some Doxygen warnings and erroneous comments; Add comments.
* Replaced find dialog with wxFormBuilder version.
* New find dialog is modeless, supports more advanced search features,
remembers it's last position, size, search history, and search settings,
and implements initial support for replacing.
* Added Shift+F5 hot key to search for next DRC marker. F5 now just
repeats previous search.
* Minor cosmetic enhancements to label edit dialog.
* Remove tab from grid size text printf to fix toolbar grid combobox
display in wxGTK.
* Updated my TODO list items.
