Extend makefaup1090 Makefile rules

Add install options
* 'make all' compile faup1090
* 'make install-faup1090' install faup1090
* 'make install-dump1090' install dump1090
* 'make install-autostart' make dump1090 autostart upon boot
* 'make full-install' all of the above

Update .gitignore to ignore faup1090 and view1090.
