added "land" command.

mavflightview: exclude positions very close to 0,0
mavflightview: show WP numbers on map
console: display rangefinder status
mavflightview: extra mission from DF logs
added select_timeout to settings
misc: added changealt command

options: Allow multiple --cmd arguments to be specified as arguments

implicitly ignoring all but the the last --cmd.
mavproxy_misc: Added "land" and "land abort" commands.
removed old land command
Add *.egg-info to .gitignore
