This was a crude hack that appends the library URN ordinal to the name of
the footprint so that it can be correctly looked up by the "element" node.
The Eagle XML DTD does not make it clear how the URN "ASSET_ID" and
"VERSION" are used to look up the appropriate "ASSET_TYPE" so this is a
best guess and seems to work correctly.
The inferred edge clearance dialog had to be disabled when importing third
party boards because on GTK (and possibly other platforms) the dialog would
completely hang KiCad preventing the imported board and possible schematic
from being saved.
