* Disable save library command when user does not have permission to write
the active library.
* Append the active library file name displayed in the title bar with read
only when the user does not have write permission.
* Test the selected folder permissions when user chooses the save library
as command.
* The obligatory coding style policy fixes.
* Use C++ map in component library instead of boost::ptr_vector.
* Drop Boost pointer containers for standard C++ containers.
* Moved duplicate name user interface elements from library object to
library editor.
* Added code to support direct addition and replacement of component
alias objects into libraries.
* Removed temporary strings used to add and remove alias objects.
* Libraries only store alias objects, components now accessed thru alias.
* Simplify library API for adding, removing, and replacing components.
* Updated edit component in library dialog and library editor to reflect
component library object changes.
* Fixed bug in library viewer when displaying alias name.
* Made a few header files compile stand alone per the new coding policy.
* Remove some dead code and the usual code formatting fixes.
* Replace EESchema sheet properties dialog with wxFormBuilder version.
* Editing an existing sheet now marks schematic as modified.
* Code style updates for some of my previous work.
* Improvements to the CMP_LIB_ENTRY object.
* Replaced symbol edit export fprintf code with wxFFile implementation.
* GCC compiler warning fix in pcbnew/drc.cpp.
* Replace component library editor new component dialog using wxFormBuilder.
* Rename component library draw items to conform to current coding standards.
* Add GetWidth() method to component library draw objects.
* Add regular expression key word search capability to component library object.
* 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.
* Add offset and block hit testing to library component objects.
* Improved search for library entries.
* Fixed library component editor component removal and addition.
* Library editor now uses wxUpdateUIEvents for updating all UI objects.
* Added version check to cmake find boost macro.
* Removed unused code in file libalias.cpp.
* Added method to WinEDA_DrawPanel to take mouse out of managed mode.
* Replaced WinEDAListBox buttons with wxStdDialogButtonSizer.
* Moved library draw entries GenCopy method to base class.
* Remove priorque.cpp and priorque.h from CMakeLists.txt.
* The usual code cleaning and uncrustification.
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.
