Fix bug 910364: When a footprint saved in a .mod file is not on front layer...

Fix bug 910364: When a footprint saved in a .mod file is not on front layer and/or not with orientation 0 degree, the Module editor load it incorrectly.
note:  the Module editor save it with default orientation and layer, but the archive function does not, so some footprints can be not editable.
TODO: modify the Archive Function to use the default layer / orientation.
