- add .DS_Store to .gitignore and remove tracked files
- copy genapkovl-bee_debug.sh to /var/tmp before mkimage (was causing "no such file" error)
- switch udhcpc to background mode (-b -t 0) so network comes up when cable connected after boot
- add -B to DROPBEAR_OPTS to allow password fallback (bee/eeb)
