Fix an issue when reading a gpcb footprint library when a .fp file has a problem. 

Now the full library loading is not aborted (and the other libraries in list are also loaded).
Only the bad .fp file(s) is not loaded.
Mainly, a .fp file load error does not throw a library load error, and this is a temporary fix.
But throwing a library error when a .fp file cannot be loaded is worst (you even cannot import a good .fp file).
