Eeschema fixes: fix  Bug #1348983 save cmp file crashes cvpcb when eeschema is opened (backannotation crashes). Happens only when some footprint names are not set (blank names).
Also fix incorrect backannotation when footprint names contain spaces (put spaces in names is always a bad idea)
* Fix minor Bug #1349058 Choose component dialog: Search field loses focus after entering a character and internationalize the dialog.
* Fix a subtle bug which prevent eeschema to read the project config file when launched from kicad manager, and when kicad.pro is not found.
