in3otd 989184b7e3 Store components data in the CompList items 
so that a separate list (LibraryComps) is not needed anymore and
information about the component and its original library can be
easily stored and retrieved.

Also changed LibraryName variable name to LibraryPath to better
reflect its usage.
