Component library editor improvements.

* Eliminate external direct manipulation of component draw item pointer.
* Add draw item remove, add, and locate methods to library component object.
* Remove redundant locate pin, field, and draw item code.
* Fix add new pin drawing bug that left initial pin draw in place.
* Improved best zoom calculations for small components.
* Library component bounding box calculation now includes fields.
* Removed unnecessary header file "libcmp.h".
* Fixed potential locate draw item bug in library editor hot key handler.
