Add a simple flask webserver to do what we want
common: A lib full of basic shit
update: A script to sync files over http
storelib: Remove requirement for path parent to exist

at the cost of worse error messages
loadlibs: automatically load API files from /lib
position: Beginnings of a lib to track relative position and do bulk movement

For now, tracks home position, relative position and facing, and monkey-patches turtle api
position: Add a general move() func that takes a relative spec and has error handling
Add a standard startup script. Not installed by default but will do so if you run it.
