* Complete comment translation for all EESchema source files.
* Complete comment translation for all 3D viewer source files.
* Rename class class_hierarchical_PIN_sheet to SCH_SHEET_PIN.
* Rename class DrawSheetStruct to SCH_SHEET.
* Tool tip capitalization fixes.
* Uncrustify and spell check comments and strings in all modified source
files.
* Library component draw items now stored in Boost ptr_vector.
* Updated draw item object comparison to include greater and less than condition.
* Moved set parts per package code from component edit dialog to component object.
* Moved set alternate body style code from component edit dialog to component object.
* Tweaked component library file draw item sort order for improved file readability.
* Documented component object draw item sort ordering.
* Moved plot code to the appropriate library component and draw item objects.
* Fixed compiler type conversion warning in plot_common.h.
* Component library objects renamed for improved readability.
* Fields now move when selected in library editor.
* Add copy constructor to all library draw and library component objects.
* Added copy constructor to EDA_BaseStruct.
* Delete base screen in WinEDA_DrawFrame destructor to prevent potential memory leak.
* Fixed memory access bug when replacing and adding a component to library.
* Moved library component block manipulation code into component object.
* Removed all of the global variables used by the library editor main window object.
* The usual code cleaning and refactoring.
* Create static component library methods to manage library list.
* Rename component library, component, and alias objects to more readable name.
* Use pointer to component instead of root name to prevent redundant library searches.
* Add append message helper to message panel that calculates string length.
* Initial ground work for merging library and library document files.
* Improved component library file load error checking.
* Minor component library editor improvements.
Moved all library entry manipulation code scattered throughout EESchema into
the component library object itself. Adding, removing, and searching is now
handled by the library object. This is the precursor to replacing the current
priority queue code.
