DIALOG_FP_LIB_TABLE: disable row resizing, get rid of tooltips on grids
Put FP_LIB_TABLE::Footprint*() functions on stage, but comment out lazy plugin lookup trick in FindRow() until these new API functions are used.
FP_LIB_TABLE::ROW::SetFullURI() does environment variable substitution up front.
We can now remove a few calls to FP_LIB_TABLE::ExpandSubstitutions( const wxString& aString )
since its being done in above function.

DIALOG_FP_LIB_TABLE now handles table to copy cut copy paste from global to
project and reverse.  Fixed a problem with cursor position management when
switching between tables.
