* 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.
* 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.
