pass in basil as arg, better bash

used to be

1. ssh into doc server
2. cd ~/src/examples
3. git pull
4. ./build/make-doc

and now, it is

1. ssh into doc server
2. cd ~src/devkit-priv
3. git pull
4. cd ~/src/examples
5. git pull
6. ./build/make-doc ~/src/devkit-priv/src/basil.js

That is, you now must pass in the path to basil.js as an argument to the make-doc script. This is because we didn't want to fully install basil on the doc server, and so we need to run `node ../devkit-priv/src/basil.js compile #...etc...`
