* 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.
